id go with main becaus ive found you have the most fun on them not trying to stick within strict lvls but then again im not a pker so its more about what you enjoy doing
Iv always enjoyed pures alot more then a Main, skilling on it is fun ect. you dont make alot of cash tough, but usually the fun parts of the game dont make you cash.
I've had many pures, and had fun with them, but I used to really enjoy my main account before silly me gave my password away That's why I have a dilemma.
Definitely go with a main! The game was made for them, and it's more fun! Although I always keep a pure on the side
*fyi.. there are already thousands of G-maul rushers out there.. so It's a hard level to succeed in!
