I am a former Albion Online player and I was planning to make an in-depth review of Albion at some point, but I guess I could share my thoughts here as well. Even I am going to share several points where Albion and SBI went wrong imo, I still do not think it is a complete failure. Albion has also done some things right and tried afterwards fix the mistakes made earlier. So I have to agree with @Vortech here and those small ranty reviews are not the whole truth.
I started to follow Albion Online when it was still in Alpha state. I watched a lot of videos, guides and comments from players. I was sold. Albion felt like a game, which offers so much things I love, and because of all that I decided to jump in to the beta test phase. Beta test was a long journey and I played it more or less almost 1,5 years. After launch I played about 9 months and I have revisited the game now and then to check out the new features, but always I have left pretty quickly because lack of interest. Here are some points what should been thought better in my opinion:
City of Caerleon as the central hub of the whole world
Caerleon is a city which was created just before launch at the end of true final beta (this was second final beta), so it was not tested properly before launch. It was superior when compared to other cities because it was a central hub for basically anything. You could fast travel from there everywhere, it had shortest way to best resources and it had the black market. So it was quite obvious that most of the player base would settle there and that slowly shriveled other cities. Most players in one place also caused a lot performance problems. Within time devs understood their mistake and now they have made corrective actions to the whole system. However, this came almost two years after release and lots of harm has been happened already.
Bad launch and first months
Official launch was horrible. Game was basically more or less unplayable for days and those problems was seen weeks and even few months after release. Characters were rubberbanding so you cannot move, server was rolled back several times and you lost your progression X time, login queue was easily 30 minutes to 2 hours, game was crashing etc. etc. So the preparations for the launch were not done properly and there was not enough time for that.
P2W or P2A or what?
Albion can be considered as P2W or at least P2Advantage. It is all about how people feels that, and there is many different opinions. I would say Albion sails somewhere in grey area with possibility to buy ingame currency with real money and with ingame currency you can buy almost everything. You can get so much help for progression with money, so it is kind of huge in game where progression is almost everything. However, you can not get everything with money and you still need to grind for that. There is also alts and islands involved the whole mess, when the game pushes people to use those and upkeep premium time on every alt separately. Albion Content creator Lewpac made a good video about Albion and P2W, it can be found from here: AO P2W
Everybody matters?
Yeah well, nice thought, but not actually right. This relates partly to elitist like @FibS mentioned. Many guilds (at least top) works like "peon" players gathered almost all the resources for the guild and then the elite players centralizes resources for their crafting alts (or guild shared alts) to get all the fame progression free and the best gear. Of course this is partly okay when these elites in some cases are fighting over territories for their guild, but still the system is used very wrong. So Albion's best crafters are shared alts and very rarely people who do that actually as main activity. I really hope that in Fractured individual crafters matter and the progression can not be boosted by other players.
Test phases better than the final version?
Many people who played Alpha and/or Beta liked one of the test versions more than the final product, and I am actually one of those people. I really liked all betas and maybe combination of those would be the best version for me. When beta 3 started, SBI was so close a really good version, but they blow it just before finish line with Caerleon concept. There was few problems in beta 2, which I would like to point out. The world was too big and there was too rarely open world PvP encounters. Also creating few separated BlackZone continents/islands was a mistake. Now one guild or alliance could conquer the whole island and after that it was quite safe place to just gather all resources without fear to encounter any resistance. So DS should keep these in mind when creating Tartaros and Syndesia.
Gold sellers
Gold sellers were at start a huge issue and they partly controlled economies and even destroyed guilds, and that way made a lot of harm to the game. People quit playing because of gold sellers and that should not happen in any case. So DS, make sure you have enough tools to work with these guys. 
These are things what came up with my mind, but like I mentioned before, there is punch of good things in Albion too why I do not think it is a complete failure. I always liked the SBI as a company and their workers, they were nice and interacted a lot with community. They have also done awesome videos and news. I love the destiny board concept, gear system with tiers and enchants, "you are what you were" model, OWPvP, resource bosses and The Black Market. On top of that I kinda miss my "support bruiser" character with Demonic staff, Mercenary leather jacket, Guardian plate boots and Mage/Cleric cloth cowl…
