Rotating War Tactics
I know that Kabam is revamping war (which is much needed) but I thought I'd throw a nugget out there to consider in the interim or even if they decided to bring tactics back (which they shouldn't lol).
Make alliances have to use all of the tactics on a rotating system. So if an alliance uses Flow, then they can't use Flow again until they've used all of the other tactics. And just have them rotate per use. If you use Stubborn, then it becomes unavailable again until you've used the other tactics. etc etc
This would help with "Flow Wars" as they are right now. Let's face it, attacker tactics did nothing. But a good rotating system will bring some variety back to war and you get to see different scenarios etc instead of the same old Mojo boss etc.
Just a thought ... it would force alliances to have to really consider when to break out their favorite tactic during the season if it stands to impact their rating.
