Sooo marks are just a worse version of a curse ???

lol

They are more annoying to use, but offer very different utility that is hard to find else where.

the big downside is they are simply more difficult to automate, practically useless for anything other than bosses

mostly because if you aren't killing everything other than bosses instantly your build is shit.

Which means you have this dead skill slot for 99% of everything you fight.

it also does not help that marks in general favor only specific build types.
