I've used it a number of times. It is a solid ship. I'd rather have a tactician TLT hwk then a generic Y-wing every time.
I won a 14 man tournament last weekend and flew two generic rebel hwks (not with tactician). I took the stresshog also.
I took 3 generic hwks to regionals last year. Twice.
The HWK is no less durable than an x-wing. It has a turret. It's dial does suck, so you have to plan in advance. You need blockers for your hwks. I think you _need_ the stresshog, but I wouldn't fly a 4-5 ship rebel list without it.
It's fun. It can die super fast, but it is a target.
