@DuckupsI clearly understand what you've told about war coins. In my opinion war prices are a little unbalanced.
Let's have some simple math, starting with boosters cost: 500 war coins for a level1, 1000 for a level2 and 1500 for a level3. And that just for the first one you buy, then it increases. A6 war brings 6000 war coins (MAYBE: you have to win it!!). So, using 13 level1 booster -half of the activations availed in A6- means you played a loosing game. If you mix different level boosters, that's even worst (for example: 2 level3 and 7 level1 boosters = 6500 war coins).
Of course, sometimes you get war coins by repairing damages (300 each one), but I rarely had more than 1500/2000 in this way.
To not say that if you loose the war, that's a complete disaster, as you'll only get 250 war coins as price.
With these numbers, normal players are forced to create low level arenas "satellite" clubs, where to fight boring wars without using any boosters just to collect war coins. That hoping to not find a strong opposite club, otherwise you'd be wasting at least 48h to probably get 250 war coins (and, for what I saw with my mates, since some month you easily match with strong clubs even in lower arenas).
Only other ways are to buy coins with real money, or to cheat/hack.
4 level3 boosters to draw with what you'll win while you have 25 availed activations sounds a little absurd to me.
Solutions? Less activations and/or only level1 boosters in every arena and/or increased prices (at least for a win, even if it wouldn't be bad to get a little more while loosing).
