Wtp is so bad about Rage?

I have a crusader and I train with atk potions and don't have rage hotkeyed. I think it's from experience playing a dexless hermit to frown upon rage, but most people in my guild feel the same way. Other hermits, nightlords, and bowmasters always go "grrrrr" when we get raged. Because atk potions are so cheap, it seems proper etiquette for ragers to ask if party members want rage or not. I know you all are using warrior elixirs as comparison, but there are people (with expanded use slots) who use ciders instead - they are 20 atk, last 3 mins, and only cost 1k (available in Showa or from Mo in Phantom Forest). The bad thing is that they take up one slot each, but for bowmasters who don't need to lug around arrows in their inventory, they work well. And for hermits/nightlords with maxed alchemist, they last a decent amount of time. Just fill up on them before you go training and you can gain inventory slots while you train each time you use one.

But for that sin, I doubt she was using an apple. That was for shock value for the sake of argument. As people have mentioned before, you can't use potion in waiting room or during the battle. She would've had to use it outside with no idea if the leader could get a battle instantly. When I CPQed, I didn't mind using a warrior elixir before entering a waiting room, but using an apple is really pointless.

CPQ is meso-free training. You get all the pots you need inside and you can't use your own pots anyway. Using 5k for a warrior elixir before going inside isn't much when you consider you're not using any mp/hp pots inside.
