I understand the ruleset that is put on HO in all metagames, and how there are restrictions that reduce the viability of many would-be threats. The main problem I have is that there are so few viable all-out attackers in this metagame because of the presence of fur coat (chansey is one example of a really, really centralizing fur coat user) alone. Unless you are +2 poison heal facade ekiller, you can't 2hko, and without strong fighting stabs you really can't 2hko on it either. This means that if you don't have strong fighting stab, taunt, reliable recovery, or a super ridiculous high powered attack, you just can't break it. It makes HO very hard to play since you have to dedicate so many slots to beating up on stall teams with fur coat, not giving you enough room to still have a decent matchup against most offense. There are ways to beat it, sure, but they restrict teambuilding to an extent I believe is unhealthy.
No, HO is not the best playstyle in this meta, bulky offense and well made stall dominate this meta.
