Regarding the Ravena-Razazak pairing, I'm leaning towards the opinion that Ravena will be stronger. Archers and machines are destroyed by Ravena
relatively quickly, and then Ravena goes into deep defense. Freezing Cold on Steel Golems, Obsidian is supported by slightly elevated Princes and Dragons. I haven't tried this pairing on the server for a while, but I feel that Ravena still has more to offer in this pairing.
Well, I tried to simulate it, and I still feel that Ravena will be stronger. Razazak needs to have a good morale boost, and good artifacts need to drop, although even with an artifact that gives 33% magic resistance, Ravena still kills two Titans with Cold. If you have any opposing opinions, please share them.
And another pairing, Axel-Dirael, I also tried to simulate. It's a pretty interesting pairing, a true confrontation of magic against might. Axel will still be stronger. If I were playing as Axel on the server, I would play a little differently, I just showed that Dira can also win here.
