The real problem with frontlines is that people are only queueing into it for the experience/tomes. Nobody is playing front lines for fun, especially not 1/3 of the time when it's shatter.

I don't play front lines, and I love playing PvP until its 4 in the morning in the majority of games that offer it. There is nothing fun about FFXIV PvP in its current state, no rewards worth grinding out. So, they take the fun out of the equation, and they have no rewards that we actually care about. 0 + 0 = 0. No incentive for us PvPers to play it. Now, it would be fun if individual plays could shift the outcome of a game - That doesn't work in frontlines unless you're doing call outs or you're running a 4 man dark knight premade. Personally, I don't find blasting people to death with 4 dark knights fun.
