I think for button bloat they will be getting rid of a lot of skills or merging them into others, and using traits to upgrade skills in ShB. For example. Heavy Thrust. I think they will either get rid of of it and buff DRG over all damage, or they will merge it's ability into another skill. Straight Shot is another skill. They could remove that skill out right and buff BRD's natural crit rate and just have Heavy Shot randomly upgrade to Refulgent Arrow. They have already shown they can use traits to upgrade abilities like the BRD's Bite skills and MCH's Shot skills.

For me personally I hope they cut back on OGCD abilities. Double weaving OGCD abilities just doesn't like to work for me and I always end up clipping my GCDs.
