Don't know what exactly is going on here, but this in-fighting is great entertainment!
Uh, as for unpopular opinions, Hydro Pump and Fire Blast are bad moves, particularly if they are used as a Pokemon's main STAB. Due to their accuracy, they actually aren't much stronger than their weaker counterparts on average (Fire Blast has 93.5 BP on average, while Hydro pump has 88 BP on average) and their lower PP makes them worse in longer matches and in-game runs since they can't be spammed as frequently, further compounded by their lower accuracy forcing you to use the move more if they miss.
Similarly, I don't like other powerful moves with drawbacks like Flare Blitz, Close Combat,, etc. Flare Blitz's recoil is really annoying to deal with, espcially when compounded by additional chip damage like Sand, Rocky Helmet, Stealth Rock, etc. Close Combat is a bit better, but the lowered defenses can be really annoying when used by a faster Pokemon since it makes it less capable of taking neutral hits and puts it in KO ranges easier. Flare Blitz's recoil and Close Combat's low PP also makes them annoying to use in in-game since it will force you to use additional resources. Overall, I suppose these moves are more balanced by having drawbacks to make up for their higher power, but I usually opt for weaker choices in in-game runs since they don't require me to jump through additional hoops like using more Full Restores and what-not.
