Well it's not my fault people have really poor, selective memory, so that's not on me. Makes me wonder why bother talking to them even!
Well I don't even remember what mega even exist or what they look like...it's like they don't exist in my mind. ¯\_(ツ_/¯
Mallows island trial..This totem Pokémon...no fire Pokémon...my slow ass ArchOwl(dartrix). Lord
Personally I find Totem Pokémon battle to be super easy, with the exception of Mallow as that one requires me to plan carefully but not because Lurantis is hard to fight but because Trumbeak can quickly overpower my Charmeleon and I need to get it out as quickly as possible to get Lurantis to summon Castform so it can set up sunny day thus powering up my fire type moves.
I love the trials and hope they just don't replace them with gyms in US/UM. Frankly the only change I'd make is to add the missing ones into Poni.
Trials are probably still in Ultra Sun and Moon and honestly I hope that will be the last time we see them as I feel that they are an Alolan thing and I much prefer Gym as Trial just don't quite capture that feeling and fighting totem Pokémon just feel like fighting a wild Pokémon that I can't capture.
