A nod from Larian's public relations or whatever might go a long way to ironing this out. If their is indeed gear with that many +stats than we must also throw out preconceived D:OS itemization ideas. Because in OS we were level 20-ish at the end game and had ~20ish in a stat for a hybrid with good items. If adding memory slots is really 10 levels of points then yes, that is complete shit.
BUT, in D:OS you gained more points in the higher levels, that could happen here? Also, we are seeing higher numbers across the board. And we are seeing level 10 characters in the completion of the opening act? Maybe the level cap is higher as well?
So, Larian may have opted to have higher numbers in general, with smaller individual effects, to even out scaling. After all, It's easier to balance smaller steps taken more often.
Unfortunately, most of this is based on too little information. Perhaps our goal should be ironing out what our concerns are for memory and the current stating and itemization so Larian can direct a response / focus their efforts.
My concern: I always play at least one play through of a battle mage, I love the flexibility and the aesthetic and what it offers, I'm not alone in that. However, from my EA experience I do not have the ability to
a - have enough skills to live that flexibility in combat. (memory being the largest contributor)
b - have enough +stat to be effective as a party member. (since I've moved from 2.5 to at least 4 stats i need to invest in, not including the combat skill investment trade off - which seems well compromised)
c - have the itemization to support that archetype (would be helped with crafting)
