Since they are removing TP I HOPE that weaonskills will just no longer cost a resource at all. Meany you can AoE to your hearts content and Tanks can use their single target ranged attack, Tomahawk and Shield Lob, without causing them a chunk of TP. And since they are removing TP I think they have already confirmed the TP regen moves are going away.

Moves like Heavy Thrust and Hot Shot I expect to disappear. Especially Heavy Thrust.

Some of the more less used moves like Tether on RDM, the jump back move on BRD, movies like that I think will go away.

I think instead of getting new abilities we will get traits that upgrade old abilities into new ones. Which means while the rotation wont really change at least it'll look new? lol.

I "want" them to remove positionals but who knows on that one. Some people like them some people hate them.

I think they will remove Slashing, Piercing, and Blunt damage and just have Physical and Magical damage. That's HUGE speculation tho.

Maybe they will throw tanks a bone and get rid of vit accessories and have them share Maiming accessories? (Very doubtful tho.)
