most people will not be able to swallow a 50-100K orksStop wasting your Orcs on catering and use them to train Strats instead Just skip catering one time and you can train a LOT of strategists ... It´s not that bad to train them. Sure annoying, but not the end of the world... nobody says you have to make them 24/7 on a lvl 31 vic springs, but it´s easy enough to get enough of them for encounters with 5 LR enemies... I keep 500 squads or so around, just by not wasting them (as you suggest) and training them when I don´t train dogs or dryads. It´s not an issue at all.
and that would give you like 20-40 troops (ok more with 3 bears and level 30 sapiens but that should not be a standard in any shape, way or form)
I sometimes waste 500 troops on like 5 provinces.
So why go trough the effort of making them?
other players use a lot less units, but they also make a lot less orks and are in dire need for those orks for upgrades and research
They just do not have spare orks to waste. and I can't make them in enough quantities
