I really love Champion. I REALLY love playing this spec. The drawback to this is that it's mostly designed as an "AoE spec" and I get people telling me that I should be taking Paragon instead.
However, I really don't like Paragon, because I suck at it. I always seem to get things out of sync, and if I lose touch-time with a boss... well... I'm pretty boned. On the flipside, I'm rather adept at my 61champ 11para 4temp spec (because the long-term melee player in me cannot live without an interrupt) and it comes very naturally to me. I enjoy it thoroughly and can pump out enough hurt in my ghetto LFD expert pugs to ensure I'm a worthwhile DPS slot.
So I guess my question is: exactly how wide is the gap between Champ and other specs when it comes to single target? I can't tell myself because I play all the other specs really quite poorly, and I can't get an accurate indication. If I plan on playing casually - say. LFD'ing experts and maybe doing some raids here and there - how long can I get away with playing Champ exclusively? Or is the gap wide enough that I'm really gimping myself by not learning to play Para properly?
