1) They're not supposed to be super strong ehile the Necromancer is on lvl 1. You can't expect that to happen.
3) It is not enough to say "add some tactics"! Express your thoughts of what the abilities shouel be.
4) And then you would only have economical buildings on settlements. Have you noticed that every faction can build one Unit Production building on settlements. That's supposed to be like that. Besides if it moves to outpost that would mean a higher cost of the building itself and harder to level up Sauron (since for one level it is required to train one unit of Cirith Ungol).
6) In the new patch 4.5 all factions will receive additional defensive building option.
7) Mumakil can receive War Paints and Banner Carrier upgrades when Influence of Sauron is cast on Tribute Camp.
8) If there is to be added additional troops for summoning, that ability would need to cost more power points so which spellbook spell will be removed?
9) Grond is the most powerful siege engine on Middle Earth
10) That is in the base of Mordor strategy - if the cost of orcs would be increased then the whole Mordor system would need to be reworked (cost of heroes, upgrades etc)
12) I think the spellbook is quite fine. If you have some thoughts about the spells then write them down.
