Cooldown support gems

A new support gem that would when linked to a active dmg gem increase its dmg for lets say 300%, but at the same time it will add a cooldown of 3 seconds.
Every two levels it will add another +100% of dmg and a cool down of +1 second.

Normally this is just a rough thought, it would need to be balanced a lot better, but the thought behind this is to give another way of customization and play style that some people want, and it will make possible to use nuke spells (huge dmg skills at less intervals) for every gem.


For people that like it, it will be more interesting and possible to use skills that have huge dmg spikes, so lets say a ice nova that does ton of dmg, but you can cast it only once in 10 sec.

The leveling of the gems will make it possible to scale the dmg and have different cooldowns that you can use for diferent skills. So you can have skills with one cooldown gem on lvl 1 where you can cast it every 3 sec, and another on level 10 where you cast it every 7 sec.

I do agree spikey damage builds could use more support. Although the problem with them has always been reflect mobs.

In any case, it's not a bad idea.
