These are the proper maxes and the recommended minimum I would take to ensure 0 losses.

About 1 catapult for 1 cavalry. Need to take down cavalry preferably in 2 turns. Another trick is to move catapult forward once and attack. Next, wait and attack. Just before the cavalry reach, move back and attack. If archers are going to come within range, move back and attack. You may be able to use fewer catapults.

Oasis Income:

Starting at level one: 100 / 200 / 350 / 550 / 850 / 1250 / 1900 / 2700 / 3700 and the rare level 10 oasis is 5000 per hour

I could use 500 cats to take over an oasis without any shooting tech AND not lose any troops. These values are not fixed. Also I used only 4 cats to take over a level 1 oasis FYI idk where u got 8 from.

I think they are rough guides really, so they you don't have any casualties.. Other players may have different experiences, just gives an idea as to what to expect really!
