Alright, apparently this is ok to do. But it shouldn't be.
T Z E (on low) boosted to his level from BVB and PVP.
Proof is here:
I have 201445 exp on low.
T Z E has 610381 on low.
That's a 408,936 exp difference. Normally this would be fine, but...
I've won 1541 sector games on low.
T Z E has won 970 sector games on low.
This wouldn't matter normally because he could've leached from a higher level, but 600 games is a HUGE difference.
T Z E also has 60 wins in BVB and 99 wins in PVP with only 7 losses in BVB and 26 in PVP.
I hate how people can easily get to a high level on low from BVB when becoming a high level should be an accomplishment.
