The short end of it is, get your PVP fix elsewhere if you are SRS BSNS.

But that doesn't mean you can't play Frontlines casually for fun. I do recommend you try it out, doesn't hurt to queue up for frontlines at the same time as other duties you might be doing.

P.S.: Their "solid plans" involve continuing "faction based combat" (tied to your Grand Company), a serious issue most people don't like.
