Having no limits on professions would result in:
A- Anyone doing PvE HL would be FORCED to level up EVERY profession in order to be 100% optimized for raids.
B- You would have to spend MONTHS (or less, but you'll have to pay a shit load more) leveling them all.
C- It would be extremely expensive and you'll probably have to farm gold in order to pay for your professions (which some will remain useless apart from the profession bonus).
D- The economy would drop. What's the point of selling X amount of something if that guy can make it himself ? Jewelcrafters that make livings off of cutting and selling gems won't be able too as it won't be needed !
I don't do dailys, they depress me. I make gold through cloth making with my mage and it's far from enough (even with the cd I can probably make 250g per 4days which buys flasks and potions for 4days
)
I wouldn't mind seeing the bar raised up to 3 though, could be interesting but blizzard will have to be very careful with it.
