WoW's trees are deceptive, in that if you choose a Class / Role, there is an absolute best / optimal build in your talent tree where if you don't do this build in the tree, you're Class Build is actually weaker in comparison to everyone else with that build.
It doesn't offer choices where you can either have these "talent trees" or not, you NEED them. There isn't a choice, you either have them or you suck. This is NOT what I want to see happen to MW:O.
In that regard, the idea behind the tree is to add
optional, non-essential quirks or perks to your mech that won't make a cut and dry "you need this or your build sucks" mentality that WoW does.
Now, that is not to say a more complex tree is a bad thing, but it must be done right or it will result in the illusion of choice kind of garbage Blizzard churns out.
