Vanesamei, the thing about persians is going like this:
1) I am player who only cares about cc points and nothing else.
2) I care about troops and less about cc.
If you do not care about troops and expect to get payloads after payloads with decent loss then this is the strategy for you. Use all units available, use max guardiands + potions + boosts, they all help. Then run positions of 150-180 first and then 200+ for a reward (when you feel it). If you just run 220+ positions then you will lose troops faster than you can get. That's the problem. This method gives you solid points and you can do any coa requirement. Even in Death INC. coa , with this trick you are safe. Also remember to fill your resources. If you want off troops only --> play def positions and then run 1 off to get payload (after like 5-6 hits, depends what rewards say). Same goes for def just opposite. Do off and then def as the last. This will give you huge def at the expense of losing offense.
2) If you really care about troops, then the trick is to not use horses in any way. Use only like 200-1000 horses just enough so they cover the bonuses from fighting persians cavarly and other units. With mixing you lose less. But do not bring every horse, just a little bit as I said.
Then do positions with rest of the army and do lower positions as bigger ones will surely deplete everything you've got. The trickier method but this one lets you keep tons of horses instead of spending them.
I have around 100k mounted peltast from this method. You always want to get horses as payload. If you get phalax --> continue doing pp until horses arrive. You can get up to 48-52k mounted peltast as a reward. It depends how the system is going to give you a payload. Sometimes you cannot get a reward after 20 positions which means that the system is preparing something. Either huge phalax or horses.
I once didn't get a payload in about 25 positions. I got mad but finally got around 50k+ horses. Is it worth? Well the def counter stayed the same (if not less) but hey, at least horses...
These are the ones I call ''lucky'' payloads. Where system doesn't give you a payload until 20+ positions lmao. But usually it gives after 5-6.
Have fun doing PP. Don't expect to get much units tho, my unit counter was max 365k units on one account. Here it is almost 200k. Just play for fun and don't think about it. Enjoy it casually.
