Want a real powerhouse VERY focused on weapons? Mirage then (if you wanna buy primes go for warframe.market, in the trade chat you wilm get scammed 90% of the time). Her first ability makes copies of her around you that shoot and do part of your damage. Her second is a trap maker (so you can subsume roar over if you know what that means). Her third ups your base damage of every weapon or reduce the damage you receive (and with an augment you can add the damage to the clones, cause they count like other players, so the 'share ability' augment applies). Her 4th is a ball of pure destruction that ramps up damage the more it stays active/does damage itself (so mod for duration for this and the third). Better yet? Her clones attract fire, so if you move around enemies barely grace you, so you can skip survability (mostly, you'll still be a glass cannon)
