I just switched to dedicated arbamolester and I have to say that it is pretty irrelevant. I switched because I wanted to be a counter sniper. I figured with a +3 Arb and +1 Bolts I could one shot archers and other xbowers. To my surprise, body shots don't 1 shot archers, and it is surprising how they can survive 96 damage while wearing around 20 body armor. The only players I can consistently 1 shot are low level players, and of course if I score a headshot. Some may argue that no class should have the ability to 1 shot, but considering that an arbalest player is extremely vulnerable between shots it's a significant trade-off. A dedicated archer can 2 shot just as easily as I can, but they're a Gatling gun compared to me.
The other problem is that in my experience, with a 15/24 build and 5 power strike, I feel like I'm playing Glance Glance Revolution. Unless I use a pierce or blunt weapon and I happen to run into the one out of 10,000 strength builds roaming NA, I'll glance and that's all she wrote. I use a +3 Long Espada and if they are packing heavy armor, I'm boned. Sure, the stab is awesome and I have success with it, but being a 1 trick pony is easy to counter. I like swords because they are cooler, give me some range and I'm less likely to be s key hero'd while in melee, and I would really like to keep using them instead of selling out and grabbing a steel pick.
I'm not going to switch back to melee though. Being melee for 9 gens got boring and I wanted something new and challenging. The challenge is bringing the fun back to the game for me, but some tweaks are certainly needed.
