I think 1:1 with increased skill slots as suggested by Naqel is the superior idea.
http://larian.com/forums/ubbthreads.php?ubb=showflat&Number=587638&page=1The devs are trying something new with combat skills and abilities. Any solution that ties memory cost to ability investment is essentially the same as what they had before (but then it was AP cost in a big bad bar)
I personally like the new direction. It needs tweaking. And 1:1 is easy to tweak, and changing/increasing point costs for spells is EASY and allows even more variety. Making rain and rejuv a 1 cost skill but hail strike costs 2 makes some immediate sense. You also DON'T need to change current memory on items and memory on level up or starting memory.
Starting with only 5 slots and poor gear is needlessly annoying for the first few hours. Having the chance to put a few quality of life skills on my bar right at the get go without changing the overall scaling will make many of the players who haven't put as many hours as Limz has, to 'stress the system" as he likes to say, feel more adaptable and less limited while maintaining the balance of the rest of the game.
I don't think the combat skills NEED mem slot buffs (though if they did, Naqel is good on this one too). But they do need to be more fun than +#'s. +#'s aren't all that fun. Not when you're seeing them for the first or hundreth time.
