t/m ops are fine in power, assuming a 90%+ success rate. problem being is that hybrids can op almost as well and sometimes better, at the risk of being chained or massacred in war. In ghettoland this is less of a risk, and elf/halfer hybrids can do quite well, as can any attacker with good wpa/tpa. the ops wind up being superfluous in ghetto play, assuming they're assigned correctly in the first place.
ghettoland t/ms tend to be incredibly selfish cancers on their kingdoms, beyond the game's mechanics. no t/ms often works well for kingdoms that want to build up, especially now that there is an easy option for a/m that almost anyone can use, and is better at spamming the duration spells ghetto t/ms wind up doing anyway.
