Up until this point, on my map I haven't seen a single tier 2 or 3 good, it's all tier 1. I'm waiting until my tome of secrets is level 3 to continue. These events crush me in supplies, and I need that 12k in supplies per scout. woot!
With his gamestyle he will need Orcs in tournaments before world map...The resources you need to cater in tournaments depend on your squad size. That's why it's possible to need Orcs on the World Map yet not need them in tournaments.
thats exactly how i play aswell, all autocombat with an exception on high lvl provinces on high star ratingI'm too lazy to calc all that stuff, and go easy way: if I loose less than one squad => it worth fighting, if more than 2.5 => better use catering/negotiation, in between - depends on how low I'm on troops or goods. But that require experience to predict how many troops you would loose.
