Just take a look at that healthbar... image - One Balance to Rule Them All (v0.2) mod for Lord of the Rings: War of the Ring

In original WoTR, you'd train four anti-rush units then zoom all the way off to Tier 4 to start training all your lategame Huorn spams. But what if you made the tier upgrade prices and times more on the order of standard RTSes - expensive and long - and made earlygame units actually worth training? And what if you gave these upgraded buildings powerful towers? And what if these higher tiers unlocked upgrades for early tier units, allowing earlygame units to still be good if not better than lategame units? And what if you gave some useless units some much-needed care and turned them into powerful monstrosities? And what if you were to completely overhaul Fate Powers and make them useful, as opposed to Ents and Balrogs? And what if you were to release it all as a mod - One Balance to Rule them All?
