Now, like I said, I don't want to bash Pyro as it does have its uses obviously. But if I had to choose one or the other in Arena, I'd almost always pick Ragnaros. The consistent damage every turn, even if random, and the fact that it will at worst be a 1:1 card trade with the opponent outweighs in most situations to be the idea that I can do more damage in a non-random fashion but only one time, and lose card advantage in the process.
And like I said I would always choose Pyroblast.
Neither of us are wrong here. You just value the cards differently to me. That's ok, as we're both allowed to have our own opinion. And we both explained very well why we prefer the card we chose.
There is no argument here. Your choice is NOT better than mine. It's just different to mine. And we each have our reasons for choosing so. I don't expect you to choose pyro over Ragnoras. You like Ragnoras and that's ok. I do however ask that can you accept that it's not about you or me being right. In an arena draft Pyro/Ragnoras/some bad card, you'd choose Ragnoras and most times I'd probably choose Pyro and neither of us is wrong. As long as we both use the card we chose well we are both winners.
