Give up, only Main Mara players actually know how unfair it's for all other classes have self-heal and we not.
The others who do not main Mara will always come up with some stupid reason they don't even know what are talking about to say " Oh but they have good defensive abilities ", yeah, guess what buddy, all classes have at least 1 defensive ability too =O !!!
Let's come up simple and with facts:
All classes have their self-heal.
Mara's don't, never had, not even in the early game when they were the worst class to play with until they got some buffs. So it's clear that their self-heal is missing not because they have other abilities to use, but more of a flaw on the class build up that it has carried to this day way back then. Heal is a really specific kind of ability, you can't mix defensive and self-healing and cc's and attack abilities and stealth abilities, one thing does not remove the other of the table. Therefore, saying one can't have a self-heal because he has self-defense ability does not add.
It's not ask for much, when it comes to self-heal. If you are against it, it's just because you want to hate on other class or try to make sure you have an advantage over.
It's not a matter of opinion anymore, it's a fact, when all other classes have it, you are bound to add to Warrior class as well.
At least self-heal is the one basic ability you will get from a Warrior in any friggin MMO.
