I'll admit I don't like when my Pokemon are hit by them though..even though they have extremely accuracy rates like around 30 but I guess there are plenty of combinations with them like using Lock-On before the move..but anyway I wouldn't say I love them or the other way around,but I'll always try to be aware if one a certain opponent might have one..the only time I'd actually consider using one is what I said before is in a combo like with Lock On..so I guess I don't mind them.

Edit:Although If they're overused in one battle and keep hitting that might be a different story..

I like them as long as i'm not trying to catch said pokemon
