Why is the Aran class so unpopular?

I'm not saying that it's hard to maintain, the problem is that unlike Xenon, kaiser and Demon slayer. Our "combo points" are wasted if we exceed the amount required by the skill, I just hate that. And I only have 14k HP as a lvl 200, just look at a lvl 200 Wind archer in KMS they have 9k HP clean, we need more HP or at least something that cancel debuffs that stop Drain from working for example stuns that are way too long, you could make a buff that reduces the duration of debuffs, you could even convert it into a link skill if you wish. My problem with Aran is that the majority of our mechanics are outdated, they aren't suitable for the new bosses or aren't as effective as other classes. For example I always wondered why they cap the buffs from combo at 100, if you get to 3000 combos that's an achievement you should be rewarded for it, a friend (another lvl 200 Aran btw) told me that a cool way to fix it was too give big increases every 100 combos, for example he said that it would be cool to get -10% damage from DR every 100 Combos and that at 1000 Combos it would just work like Kaiser's transformation, to not exploit it you could force a combo reset like for example having to cast a buff that spend all combos no matter what. I think that his solution isn't OP at all, because we have no bind or crash, and we have to work to get it.

Oh I totally missed your point there, sorry. Yah I agree.

EDIT:

Another reason why Arans are losing popularity just came to my mind. Aran skillbooks are a pain to get at the moment, so looking at how easy the new classes are, many new players are not used to actually having to do something to get skills.
