Dunno what planet you droped off of, but Albion chars have NEVER been as good as you make them out to be. The only thing Albion has EVER had going for it was its population, and i consider that as just balance. The tanks suck, which is why the main tank class " armsman " is becoming rare on the battlefield. What the hell good is a tank that can be mezzed then fried before he/she could even consider engaging anyone?
Hibs are not supposed to be good tanks, but they got some boss ones. Mids are not supposed to be good casters, but they got some boss ones. Albion was always the ones in the middle, not as good as Hibs in magic but better than mids, not as good as mids in melee but better than hibs. But all that has changed, thnx to pop bonuses. Now, on almost all servors, hibs and mids level faster, get ML,s faster, RP,s, RSP,s, and BP,s faster. And trust me, i know how much those ML,s can help as well as those RSP,s in RvR.
As to it being hard to level chars in midgard, well, i see everyday in Albion, folks having a hard time leveling. Its not just midgard, its all realms where there is no support from higher lvl chars to help lower lvl players lvl up. And it doesn't take long for those younguns to get disenchanted with the game and quit.
Anyway, without the numbers, about 2 to 1, Albions wouldnt stand a chance vs mids or hibs. And there are some mid and hib classes that can easily wipe out 3 grps of Albs as easy as peeling a banana. I see one grp of hibs, a caster grp, dunno what they are, but on my servor, you better have at least 4 grps or 2 grps of the highest ranked RvRers to take them down. They routinely shred 3 grps of Albs with ease.
