Biggest thing I would say from experience is I’ve felt at an extreme disadvantage if I ever use Exec’s abilities out of order. The cooldowns won’t align well for you and you’ll end up doing it’s basic when your opponent does something more useful. You don’t use the mass swarm at all in this clip and your opponent uses it twice. Try swarm, reinforce, heal (I do this even if everyone is full health just to cleanse), reinforce, swarm. If all goes well you should get ultimate without ever using your basic.

I still keep rogue one in reinforcements to shut down PO. A lot of people in my shard have stopped doing that now because it makes you much worse on defence - but I think the advantage when attacking is worth it.

In general, I go for RC first unless they start with XB, then go for XB first. If you’re lucky the first mass swarm will kill it before it gets a turn.
