I’d disagree with you.
Sure white spells made it easier to avoid mages in certain circumstances but it also made impossible certain actions requiring the invisible umbrella of the blue mage to cancel cloaks and removing the cooldown, which is a crucial hunter skill.
Mage towers have the role of syphoning rage. You either need to get rid of the mage towers with a lead Dragon or use your spells wisely (cloak, freeze, deflection, absorption) to avoid mage shots.
Mage towers have a huge power: preventing the opponent from using powerful or disabling spells.
High level mages have comparatively low dps but if you’re hitting up it certainly adds up. They also have an important protective role:
Blue prevents the Dragon from using blue spells or cancelling them. Red protects the towers next to it and prevent spells from landing. Red mage supershot (blue mage I’m not sure) vaporises certain temporary summons (I don’t have a list).
About your solution: what’s the point of a blue and red mage with more pew pew? A static color shield with a bite? If you remove the threat of the mage shots freezing and draining rage what do you do of research about mage shots draining more rage? What will you do defending against dragons who were only vulnerable if you managed to rage drain them and mostly when the opponent messed up (or in my case panicked )?
In conclusion I think mages are in the right place. Real lifesavers in smart defenses, frustratingly annoying in attacks, with reasonable power despite their lack of damage output.
Touching them up would make them overkill and a veritable headache for player who have played for years.
If the grammar is lackluster or if there are any typos I apologize, I’m typing this with very little sleep.
Edit: also that’s one of the most fun part of the game to learn to avoid mage shots in the nick of time and playing with blue mages with any blue-cloaked hunter. 'Specially Hauheset the Beautiful Queen of all Dragons
