Now basically what we have though is a pick and choose clash of abilities for classes to mesh together with very little abilities set as class specific. I pointed out that instead of this I would much rather see a Marauder retain all weaponskills(Unless of course they do away with a Marauder only wielding a Great Axe. In that case only specific one's should end up being class specific.) and most abilities regarding TP, but I can see giving up Bloodbath, Defender, Disorient, and Warmonger.(This ability I can only see useful for a Gladiator.)
I agree with you that weaponskills need to be a LOT more attached to a weapon or a weapon type. It's just insane that I'm shooting Skull Sunders with my bow and striking Wide Volleys with my knuckles. But as system goes now it's as DarkStar stated: Borrowing weaponskills from other classes is very handy or a must, if you want to farm those horns for example and you have too little time to get a party to help with it. Getting class exclusive skills and giving them more meaning than current big mass of dull animations that just do more damage, apart from the cream everyone takes as you stated.

Now where I do agree with you is that they need to make some better damn abilities that you can obtain through guild marks. Quite frankly as I said I only see one good one and that's the Conjurer's Fast Cast.
Well there are some good ones as well like Multishot and Out of Sight for archer, Self Preservation for gladiator, Intimidation for marauder (Altough I think it suits gladiator more). It's also true that we definitely need more class spesific skills to get from them and they need to be badass enough to get people feel their class is unique from others and stick to it.

With this way I said I could really see a clearly more defined class, and hell it's not perfect so it's open for debate. What I want to know is what you think as well?
This is main point I'm concerned about the future of battle system. I think classes don't need to be too defined for one role like tanking or healing, but ridiculous ideas like gladiator tank also easily healing itself. It's clear that now when people got their hands on Cure/Sacrifice with all classes their not easily willing to let go of them. I think all classes could get multiple choices of roles for them, like gladiator DD, but then it shouldn't be able to define itself as a tank the same time.
