We really need a useful master trait on explosive to make engi compete with all other dps classes on PVE. For WvW, boon removal is a good idea, like "explosive skills remove a boon, three sec recharge". However, it wouldn't change anything on PVE HL. Engi needs to be the best at something, or to have a unique party buff without sacrificing too much on Dps. We also need grenades to have better radius, better speed and only hit once. At the moment, because of this, it cannot be used on WvW unless you want to kill yourself : 5x3 hits : 15x retal damage back to you on each launch. I have seen another post about elixir S weeks ago. On WvW at least, we have to be able to move away from the fight when using it. At the moment, the amount of cripple / chill condition is really high and you cannot escape without dodging to go away (which is sad because you are supposed to be invincible and can not use any skill). Maybe we could add resistance when using elixir S ?
