Just saying this again:
1) Yes it sucks we have to spam trace missile / grav rounds... but we have to in order to even use our other abilities as they rely off the procs from those abilities.
2) In a 1v1 situation, if you interrupt or stun us during the casting of said abilities, we're pretty much screwed because of aforementioned number 1, as well as having only few abilities to get you off of us.
3) Most classes have what, an 8 second ability to lock us out for 4 seconds? Along with stuns? Use them more when we are standing there launching our tracer missiles, lock us out of it, and then just pound on us. We're not powertechs or vanguards, and therefore if you stop those abilities and get up in my grill, chances are I don't have my CD's to get you off me, or do enough damage in melee.
4) Yes it sucks in a big pvp battle to be hit by said abilities, but in any other battle or 2v1, 2v2, 1v1, it's so easy to stop us from casting, especially if you run in our melee range, we're pretty much useless.
