PvP (Gunslinger Sub): - Where do I start, boulder crush is our only stun which requires switching envoy's path, our accuracy is bad (also a con) so we miss quite a lot, we are melee.. lol, and aftershock aka your 3second stun is absolutely horrible. BASICALLY, if you stun first you win, if you don't you lose. However, this is not a PvP build anyway and you will still do fine on wizards and katars who don't know what they're doing (they can ALWAYS stun first if they want to which gives them an advantage).
Due to the fact that we are melee, it may require more skill and you being higher level and geared to start being tanky like the Pros section says. At low level, some boss AOE may be hard to dodge and may 1-2 shot you like the 2nd boss Ryan in AT (his yellow rings). Our skills have a slower cast time as well so if you don't jump cast you may be stuck in the AOE and will have to tank it. We're not a warbow with 27meter range, we are right under the boss so you will OBVIOUSLY get hit more and have to watch out since you're more likely getting hit. Highly geared and high level Ravagers don't need to worry too much about this CON, though, except for typhoon and the new 65 dungeon.
Terrible damage on non-crits, make sure you hit 60% crit one way or another!
