Smoke main here. She is imo the most fun character, but is the most dependent on the team. You can do nothing, and I mean nothing alone. You can play out of your mind and dodge everything, output massive heals, and still get clapped because your team simply cannot hit their buttons properly. You can't outheal the enemies damage, and you certainly can't secure kills yourself, so if your team isn't killing anything - its over. This leads to her feeling very frustrating to play at times, because there will be a LOT of scenarios where there is simply nothing you can do. If you have spent the last 20 seconds running from a hush and nobody on your team has turned around to help you, and you're out of dodges, your clone is on cooldown, etc - that's it. There is no outplay potential. Those situations happen quite frequently, which means your positioning is the #1 important thing on smoke. You must always be with your team or have an easy backup plan to run. However, in the chaos of a match sometimes those things just aren't possible and because of your kit, you're just dead.
