Charr for rifle & Charrzooka?
Nothing wrong with going charr for the cool toys they get. The charrzooka is hands down my favorite racial skill in the whole game. I use it on my engineer as it covers the engineer’s lack of a long range kit, not sure how well it’d mesh with a rifle warrior but it couldn’t be too bad.
It’s just up to you if you want two of the same class, otherwise, as I said an engineer is a good choice as well since the charrzooka fills a gap in their skill set rather nicely.
I just started using my Charrzooka and I love it. It has nice ranged AoE, a good knockback spread, a good knockdown/jump back power, and 2 decent damage dealers. I use it a lot in WvW as an impromptu arrow cart to either rain fire down from walls or to hit the cannons on walls my rifle can’t get.
I use rifle and axe/mace. The rifle is good ranged for 1 on 1, the charrzooka is good for multiple foes. There is a bit of a cooldown on it so you can use the rifle during that period. But I highly recommend it.
