What max level server should i go for, if i wanted to solo all the MVPs ? Like Bio lab 3 , thanatos, beelzebub and so on ?
well, hard to say.
depends a bit on the jobclass and the items you have.
but, to solo most stuff maxlvl 500 and max stats 255 is ok (except you'll try to solo all those with some SuNo =P )
but with some sniper/assa i guess you're ok with above mentioned.
Depends by many factors ...
How easy you can:
• reach max ASPD/instant cast
• get gears for MvPing (AK cards and such)
• atcommands avaible (warp, jump, mobsearch)
• MvP arenas (with a limited map space and the chance to select wich MvP summon)
In my honest opinion is not strictly related to max lvl, but the features above.
Anyway ... With Renewal I played few servers with max lvl 175 and was pretty easy to solo MvPs (including Belze, Gloom or Ifrit; just need healing items). Into Pre- RE should be even easier ... old MvPs have less HP so needs less time/hits to be killed.
Is all about the time and patience you wanna invest on it; if you just wanna have fun check for some max lvl/stats 150~255 High Rate server and you're done.
If you really want to solo everything, I would say that 150 should be already good enough for that since pretty much all can be solo'd with the right chars dual'd for buffs at a ~80.
yeah, u need a higher stats for this
