Why aren't debuffs that cannot be extended listed on the debuff or on the debuff extender skill? Soulless for example seems like an amazing champ on paper but when you finally draw him (likely spending money on shards), build him, and put him into battle you find out he doesn't extend freezes, provokes, and fears to name a few. Nowhere does it say that. It should be on the tooltip or it's false advertisement. People pay money to draw these champs.
-Minotaur's Dazed debuff specifically says "The duration of this debuff cannot be increased."
-You also have "It will not extend [Stun], [Sleep], [Freeze], [Provoke], [Fear], [True Fear], or [Bomb] debuffs." on masteries like Master Hexer.
These are two simple solutions that you have already implemented so to not add them to skill tooltips seems intentionally misleading for monetary gain. Please fix this.
