Seer rebuild! Read it!
Okay, we all like playing with Seer. Is amazing playing with legal hack, but that hero isn't for that game. First, u cannot hide, u cannot heal and he can detect all ur team. Whatever, what i mean is that they didn't had any idea what they are doing, when releasing seer. They just dropped they blood and crypto in the trash. Respawn should consider rebuild that hero from stratch or nerf him like hell. I'm giving Respawn few suggestions what they need to do.
1: Remove scope's enemy scan. You should be able to scan people only with your hands while casting 1st spell.
2: Remove the effect of that spell to interrupt healing and etc.
3: Ult should be detecting people as Pulse/Signal/Heat. Like they should be visible for 1 sec, then 2 sec off, 1 sec on, 2 sec off.
4: Seer should be not able to scan heroes like Pathfinder or Rev with First spell. That's one of the things that can turn the game, cuz they won't be able to see 1 or 2 of the teammates.
That's a must for this hero or just delete him.
