We must take into consideration fact that Fractured takes inspiration from ADaD games, where "crit" would only roll on weapon attacks, no spells. No mage would ever crit with any spell, still mages were late game powerhouses.
In fractured it is imo simple: melee warrior has to 1) get into melee range to even deal any damage, but he also 2) needs to be tanky enough to stay close as long as possible. Melees balance tankiness with damage - while ranged guys can shoot all day long from distance even on running enemy, wariors must burst enemy down as soon as possible or be kited. For this they need crits, mages dont. Mages have enough time, they will kite melee with slows and stuns while nuking him with nukes. They also don´t need to be as tanky as they rely on active defence - teleports, absorb shields and not getting hit in the first place ---> they can invest talent points into offence, same with enchants. Mages can go glass cannon, melees cant.
Lets take Fireball. On int 25 one can deal 800 dmg. With PER 20 and CRIT damage talent you would get 2400 dmg/nuke. Thats one nuke that critted and it´s aoe. Or Ice spikes: if the ability can shotgun, then it deals 1750 dmg -> 5250 dmg with crit. Lets assume nuker character will probably have slotted at least two or three nukes of similar power level (one of each element), so if your opponent got some lucky crits, you´re dead. Or if he got at least one lucky crit and both other hits landed and he also has Power word: Kill (and every PVPer and their mom will), you´re also dead before you even reach him. Glass cannon mage (high INT, high PER, all into accuracy, crit damage and crit chance, only nukes + teleport + one invis reveal slotted) might delete anyone with lucky crit. Alphas and betas will tell if Im wrong.
Personally im curious about pvp, hope archetypes won´t be too unbalanced.
