Traits and the casual player.
I’m a by far not a hardcore gamer, I play this game mainly for open world pve, exploration and such…
And as soon as the game pointed out the trait system to me as well as the build system, I started using it, sure it took me getting to level 80 and alot of reading through the traits and finding ones that worked together.
But I figured it out in time, stop dumbing down a game just because a small percentage doesnt realize that the big glowing button is worth checking out, or cant be bothered to read through some minute volumes of text to try and find some synergies.
That said, anything in the open world, can be defeated using no traits at all, it wont be optimal, it wont be at all times a fun experiance because you lack substantial power, but it is possible.
And if players are pushed back by “deeper” gameplay, they probably should stay clear of RPGs, because they are built on deeper gameplay, such as character customization.
Honestly, everything you’ve described here is a non-issue. If GW2 didnt have the build variety the trait system allows for, I would’ve never stuck to it, it would’ve gotten boring REAL FAST. Half the game is getting to 80, the other half is figuring out stats and builds to venture into fractals and the like, or to try your hand at PvP.
