They will catch up with EoC faster, aint that obvious???
That all depends on the rate of content release ...
And, isn't this new idea (which I'm sort of ambivalent about, I have to admit) for sub-level-1000 players to advance faster ? - giving out a plethora of AL 500 potions allows EVERYONE (other than those at the cutting edge of EOC) to advance faster.
Still, all of this is a moot point - there are going to be 10 pots given (plus the 1 for top 100) 'cos I don't think the result of this global is in any doubt
