Ideas and suggestions.

Resistance boots in the Haven are now arguably no worse than +2 to all stats.
What I would really change is Armageddon to level 5, and I would also remove Resurrection and Teleport from the level 4 shrines.
And considering the greater connectivity compared to the Conflux (without one-sided units), the absence of a cloak and quiver, an Armageddon obtained early in a shrine (and the ability to adapt the spell in the Haven on average faster) is simply an unstoppable and very unpredictable advantage. Which can easily ruin some matches for no reason. You wouldn't want to start planning on the second week that you can't touch that particular unit, would you? This is very disadvantageous in the long run, but at the same time, it will cause some defeats that cannot be avoided.
