Despite the previous update bringing new minions, the game still doesn't support the use of minions, such as "sets".
It's very common to see mages (and archers) using elementals as a "tank" while casting powerful spells causing absurd damage, or tanks using ranged minions to complement the damage. However, there is STILL nothing that supports playing only with minions (like in the Lineage series, or FFXIV in the early days, and even some ARPGs like Titan Quest, Diablo, Last Epoch, Poe, etc.).
In my opinion, a big problem nowadays is that minions inherit ONLY the player's attributes! It would be interesting to have something like, IN ADDITION TO being based on the current attribute that does not deal damage, having a debuff on the minions based on attributes that increase damage (INT/STR/DEX) and having the damage a HUGE improvement in the minions' attributes (especially in the necromancer, because you easily lose your minions while walking... the skeleton warrior easily takes the knight's attention [which makes no sense] and the ghoul... besides the fact that it is practically IMPOSSIBLE to do a chase... because the minions are slow, and disappear when they move away.) Wow, I just got off my chest, sorry haha
