Why go back and mess with almost every encounter in T5, basically breaking it or increasing the difficulty while at the same time ignoring the 2.1 BT patch nerfs to T5?
Kael - unkillable
Al'ar - unkillable, hp still at pre 2.1 levels
Hydross adds and Hydross health still pre 2.1 levels
Leotheras now untauntable (blizzlike), whirlwind ignores armor (blizzlike), inner demons health still pre 2.1 levels, Leo health still pre 2.1 levels, Leo spends too much time whirlwinding when demon form is queued up (2.1 fix)
Morogrim ice bubbles now pop regardless of player movement (bug), adds hp still pre 2.1 levels
FLK now leashes all his mini bosses correctly (bug)
Solarian trash no longer aoe's all at once (bug), aoe damage still pre 2.1 levels, still summons too many mobs (pre 2.1), hp still at pre 2.1 levels
Not to mention the Gruul bugs you introduced after tweaking his loot table and spell frequency, why even mess with that?
What is the rationale behind cherry-pick-fixing T4 and T5 content?
