Hi
I know what you are talking about and I agree on the general problem.
The most problematic factions are Isengart, Mordor and Lorien, I'd say, because they all have a very strong lg that is close to unbeatable for some factions and they all three can camp very well.
With their much stronger lg these factions force you to finish them early on, but that is very risky, because you invest a lot of money in siegeweapons and they have the defenders advantage (towers, healing, fear effects, (Angmar walls), attacking units hit buildings instead of enemy units, and so on).
Now as far as I know one of the "goals of 4.5" was to make comebacks easier. Changes like the inflation and the central CP-upgrades help with making comebacks easier.
Also, according to
this article catapults should not be able to destroy an entire base and rams combined with infantry should storm the enemy base. The problem is, that you often can’t attack a base with rams and melee units, especially not one of the named factions: Lorien for example can build the statues that cause your units to run away all the time. Two or three of these make any ram based attack impossible. Mordor also can build the watcher expansions to make any enemy run away in fear. Unless you have a permanent fear resistance in form of a hero you can’t attack.
Isengart has strong towers and warg expansions (you basically can’t kill the warg, as soon as the first one dies another one spawns) and can produce a lot of units very fast.
I don’t really have an idea how to solve this problem tho.
Nerfing towers would certainly help, but it could lead to other problems (baserushes could be to strong again, like they were in MEGA).
Buffing catapults would kinda undermine the attempt of making sieges more dynamic and fun to play.
Some changes could be:
-nerfing of the warg century by adding a timer before the next warg spawns
-removing the little wall parts of Isengart and Modor bases that make it impossible to shoot over them
-giving reliable fear resistance to all factions and/or removing the fear expansions Lorien and Mordor has
giving all factions a way to permanently reveal stealthed units at range and/or changing/removing the mist upgrade of the Lorien base
Also the walls and bridges of the Lorien base has a lot of hp, maybe that could be reduced as well (or the expansions should be attackable separately).
That are my thoughts on that topic for now
Best regards,
