i like the stream lining of certain features,.. like when i play a last gen remaster i am immediately reminded how stupid save points were and how much better life with with autosaves.
but as far as the core gameplay goes,.. i like both. sometimes i want to play and easy game just to relax. sometimes i want to play a game with a lot of depth,.. mulling over a talent tree is one of my favorite things to do in a game like WoW.
just keep it fun. there is nothing worse then a system that demands a lot of attention but offers little reward. if you are going to make me manage my equipment my equipment better have a substantial influence on how my character plays with lot's of "pro/con" things to consider. there is nothing worse than managing equipment manually when the equipment is too simple like only providing a "+armor" stat so that clearly there is only 1 piece of armor worth wearing in my inventory.
