Adding More Customization In Our Abilities

I have discussed this with other people and I know this won't be a quick update but rather a big update, I don't think this suggestion has been done before but basically having more customization not just in our weapons/crafting but in some of our abilities as well.

How it would work : It would be the 4 base spells but different forms of the 4 base spells like for example where a mage will heal hp, there can be a form where mages can heal someone else's mana or create absorption for their party members instead of just healing their health(just an idea). Where as clone classes, they will also have clone skills like with the normal game having the same effect. You will remain to have 4 spells as the maximum interaction for spells is 4 and will simply be replaced with other spells(if you pick absorption as your first spell healing would be removed), you still can't use completely different spells however as it still must have like a general base style.
Ex : Mage
Spell 1 - Healing/Support skill
Spell 2 - Movement Skill
Spell 3 - Crowd Control / Main Damage Dealer
Spell 4 - Debuff

Changing these effects : you would not be able to change your abilities constantly but having a cd of around an 1hr or 2. The way you could change this may be inside your in game menu or an NPC to talk to, for a hunted mode you would need to have it off or in a safe zone in order to change your spell.

In my opinion this can add more strategy in the game and overall have very different builds and have more variety in the game in general. Although this can add more bugs and exploits it is only natural as it will normally happen if a new feature is added in game. This will most likely take like a very long time I still feel it could be a usable idea although it will take about a year or 2 I also made a list of some pro's and cons
Pros:
-More Strategy
-More variety of builds
Cons:
-Constant balancing or 1 build will turn too op and the game will just die off
-Changing some abilities may ultimately also end up in the change of armour

 

Interesting, I just don't see it being implemented

 

This would be cool, maybe there could be specific weapons for these spell forms so you could alternate between weapons to use different spells. Would add some extra skill requirement to things like guild wars and PVP battles.
