An abbreviation for "imbalanced"
Imba can be applied to a subject in gaming
(Weapon, army, race, role or job) which can be either too strong (Overpowered
, or OP) or too weak
, or UP).
Although the word IMBA can be applied to both OP and UP, it is mostly used
to describe an in-game subject which
is too strong.
A good example for imba is the job hunter in Ragnarok Online
