Why does Barrier have a shorter cooldown than ignite? It should be longer.
Hear me out on this.
Ignite encourages forward-play. It encourages trying to make a play, get a kill, going on the offensive. The "fun" kind of gameplay that we've been trying to encourage.
Barrier, on the other hand, encourages defensive play. Reactionary play. You never PLAN to use barrier. It just happens when you realize you're going to die otherwise.
Further, Barrier has more options than Ignite. Ignite is only any good if you're strong enough to kill someone. Sure, the grievous wounds is helpful in edge cases, but overall if you're in a 1v1 mid lane with Ignite the spell is only any use if you're going to try to kill your opponent. Meanwhile Barrier can be used to save yourself (or prevent damage) in general. When you get ganked / tower dove / etc... It's useful whether ahead or behind.
Ignite is only useful when not behind, and encourages active gameplay. Barrier is useful always, and encourages passive gameplay.
So why does Barrier have the shorter cooldown? Shouldn't you be punished for the safety of barrier? I feel like ignite users should get windows of opportunity where Ignite is available and Barrier isn't - not the other way around.
It just sucks when another lane is feeding and you can't get a kill 1v1 because your lane opponent has barrier whenever you go for the all in. When an ally is doing well the barrier user has an extra resource to just let that person carry, whereas ignite users needs to just try to force plays themselves.
