Warning: I didn’t read most other postings, so maybe this was already addressed!
Most of the new war conditions don’t favor the defending team like the familiar ones do. This might be good for alliances with new and/or casual players who don’t have 30 reasonably strong heroes for their attacks. But it is not good for established players and in especially not for the top100-200(?) alliances.
These new easier conditions together with Telluria losing its teeth raises the average oneshot-rate to an unusually high level. At first glance, this might sound attractive/satisfying for many players. But when you rethink, you realize that it lowers the impact of skill if more than 2/3 of the attacks are oneshots, at least half of them without really having to think. What makes it worse is the fact that a oneshot is the expected result. When you succeed, it’s fine, but as you expected it, you cannot really rejoice. On the other hand, when you lose, you have an unusually bad result and feel miserable.
In my opinion setting the difficulty level in wars to a higher lvl would accomplish two major improvements:
*The skill factor is higher because there are less autowins. Of course there would also be more autolosses, but contrary to the autowins, better decisions will lead to more points and a more weakened opponent.
*If the oneshot is not the expected result, you can really be happy if you achieve it. And you won’t be as sad if it doesn’t work out as planned.
Telluria/Vela was too strong compared to other tank options, but it wasn’t too strong in itself. Because of that instead of nerfing them (ok, the first nerf round was fine… I would have preferred seeing some buffs to other tanks or new suitable heroes.
Back to the new war rules: Generally they are very good news. But they also should favor the defending team, maybe even more than the old ones. Any symmetric rule, in especially ones that prolong the fight like “undead horde” does, benefits the attacker because the longer fight gives more decisions which even average players obviously make better than the random AI.
As noted at the beginning, maybe wars are wanted to be easier for casual players. If that is the case, I would suggest slighly different rules for alliances with different war scores. For example you could say, if the alliance has more than 100.000 war points, the defenders minions will have 12%/12%, the attacking players minions 8%/8% attack/hp. Above 125.000 war points something like 15%/15% vs 5%/5%. Obviously these numbers are not tested and just a basic suggestion.
