>>440453971)Because said mons that are punished by rocks have worse things to deal with than stealth rocks (One example out of many: The majority of the bug type mons are early game GARBAGE that have horrid stats and zero ways to be effective offensively, defensively or even just support)
2)Prior to gen 4, flying types were a great defensive backbone because they could switch in almost for free while Spikes are up, thus mitigate the chip damage and survive the incoming hits. Stealth Rocks going up reduces the endless switching that low elo people like you think is stall, and speaking of.
3)Stealth Rocks going up is one way to punish defensive playstyles and Clefable aside, the chip damage from rocks can be helpful to shorten the regenerator mons' recovery and that little damage adds up in the face of a setup sweeper
4)A grand majority of flying type mons have Roost for recovery so it's not like you're permanently fucked and staying at 75.
5)Hazards are not permanent unless you're retarded at teambuilding. Defog, Heavy-Duty Boots, Rapid Spin and even Court Change. If you know how to play the game, you'd know how to remove hazards, when to remove said hazards and the benefits of removing said hazards
