For example, the soldier has two different rocket launcher.
The basic Rocket Launcher that does loads of damage, has a huge splash range and moves moderately fast.
On the other hand, you have the Direct Hit, which does 80% more damage for 80% reduced splash range and increased speed.
You can choose to sacrifice splash (Which is a very important factor when you're playing the Soldier) for additional damage and speed, or keep the old style and deal with it.
Same goes for the pryo, you get the normal Flamethrower which does normal burn damage and with an additional airblast alt-fire included. Airblast would enable to you reflect projectiles. On the other hand, you get the Backburner, which does 100% critical on a back burn (When you're facing the back of an enemy) but has it's airblast removed.
You can choose to do additional damage by ambushing with the Backburner, or go head on and reflect bombs, grenades, rockets, softballs, jarate AND even ARROWS for an additional "Mini critical" damage returned.
Should be a factor for most games IMO, you gain some, you lose some. Situational and requires pre-planning.
If Mabinogi is going to get classes, players should be given the choice to either stay vanilla, or go chocolate (With particular debuffs that makes it less of a platable choice than vanilla unless you're used to spamming spells, arrows or running about doing melee hits.). Seriously though, a change like this would change PVP massively. No one would want to duel against the class they're weak to, especially if this were to be implemented.
Let's just say, adventurers will be vanilla, warriors would be chocolate, archers would be mint and mages be strawberry. Everyone has their own likes and hates, obviously.
Maybe, maybe perhaps if there's a winning chance for those that's more skilled... Just maybe.
I'm fine with that. Lets kill The 4 magic shields, bolt mastery, lets kill healing and make party heal usuable wihout a wand or just kill party healing, and hmm thats all i think we can afford to lose. 5 - 6 skills is enough.
The 4 magic shields actually gives decent MP buffs. Removing it would be quite a waste, I did say. Bolt Masteries would be useful for magic users. Some players prefer healing and party heal can heal wounds when mastered. They're all equally useful, just not desired at particular situations.
