"I wouldn't consider bonus actions a strategy, it's completely luck based now and it will be completely luck based after the update as well. You can't choose anything about them, other than making sure you have S ranked arks. Limiting yourself to just one will put you at a disadvantage right now, and you will gain no advantage after the update either. Just because you're "used" to having only 1 BA won't change anything as we don't 'plan' for them now, we just take what we get."
Using less bonus actions = using more strategy. You have a higher chance of requiring more strategy if you restrict your bonus actions. And this will help you for after the update.
"I can understand where you're coming from with the Stegospike, although forcing yourself to not use an arkadian that you would normally use based on it's current stats/abilities will only really benefit you after the update if you don't have a plan or can't adjust quickly."
Which is the point.
"I don't personally use Stegospike at the moment, but if I were to use it now, then I could quite easily gain the advantages of using it right now, whilst having a plan in place to replace him when the update comes out. It would take no more than a few games after the update to be pretty much fully adjusted to not having it anymore."
But the more you go without it, the better of a strategy you can develop without it. More time = better. So I've spent a lot of time without using it.
