No, that’s what players who insist draft is the “right” way do.
If Mosh is wiping your party, the majority of your party is in it.
If your party is in it, they aren’t interrupting it.
Alternatively, even without interrupt if you can whittle ETC down enough he has few safe opportunities to use it, and if used at the wrong time he just dies to anyone not in it.
If I’m Greymane against ETC and my team has no interupts I’m going to be spending most of my time in human form, not sitting on my allies and almost certainly take Cursed Bullet.
I might cat-and-mouse-lane a chunk of the game, because the enemy team is going to stay grouped with ETC to capitalize on Mosh (which is practically useless without 2+ allies nearby)
And unless I know for certain the enemy team isn’t going to be able to be near, I’m not going to bother trying to initiate on the boss, which is usually a bad enough throw pit as is, but is a nightmare when the capture point usually results in the team grouping up for a full Mosh.
There are things you can do. How you play is more important than draft, and most people can’t get that part down and instead focus on draft.
It largely impacts how you play, and the pros practice specific strategies and tactics, so that matters to them. It does have a slight impact on win rate, but as with most tier lists, it doesn’t really matter unless you’re at the top.
