BLU Suggestion: Debuffs to immune enemies

Hello dev team,

I have a suggestion, which might spice the gameplay of BLU up a bit and would likely be easy to implement. If you are planning to keep the class "limited" (which I would really advise you to review again), then why not add alternative debuffs for enemies that are immune to certain status changes (e.g. Deep Freeze or Stun).

E.g.: An enemy that is immune to Stun get's a "Tripped" debuff with the same duration instead. He will still be able move normally, but the BLU will be able to use Sharpened Knife with increased potency (250) on him. You can do the same with Deep Freeze and Petrify.

This would solve the issue with "Spam Ability X until cooldowns are ready and Song of Torment should be reapplied". It would also give him quite a DPS boost, which he really needs in my opinion.

EDIT: I have some experience with contructive suggestions in a toxic enviroment. Not only here but at other forums to (for some reason shitstorms mostly happen in online communities, at least for me). So I will save myself the stress of arguing with people that simple know "everything" better. Take this post as it is, a suggestion and do whatever pleases you with it.
