I think there should be Strong Dispell, Basic Dispell, and a "Mini Dispell"
With the current state of powercreep changes, the constant "this ability now also slows and deals damage" is getting a bit ridiculous. I think there needs to be a third dispell option, and a third dispell category.
Let me attempt to explain:
Orchid is a 3275 gold item, and should be purged by something such as manta and euls (Basic Dispell). This makes sense, have no problem with these interactions.
What I want is an item that doesnt cost 3k and has a "mini dispell active effect" which purges small things like the slow from khanda, and other small annoyances that are not major abilities. It would need a decently short cooldown similar to euls scepter and probably do nothing else to keep it affordable. Call it Skipping Rope or some shit and just have it purge slows that are minor annoyances.
It would not purge any damage ticks, but should negate the slow that comes with it, if a combined ability.
For example Ignite, or Dual Breath. Skipping Rope (or some other item that gets changed) would not stop the ignite damage, but would remove the slow debuff.
Should be self targeted, not usable on allies. (could potentially have an upgrade to purge mini buffs on enemies.)
Strong Dispell should stay the same.
Basic Dispell should stay the same.
Mini Dispell should purge (non-ultimate) movespeed slow.
Thats just me, let me know what you think, or if you have any balance things I didnt consider.
Cheers.
Edit: Another Option I have considered instead of a completely new mechanic.
1500 gold
+25ms
+150hp
Active
Sets your movement speed to your base and cannot be changed for the duration 5 seconds movement speed bonuses regained after a grace period of an additional 5 seconds. Cooldown 30.
Also Buffing Slow Resistance, or giving it to more things would be neat!
