Level 10 walls costs

OK, i m a very extreme farmer, i have maxed out all my lv9 walls for town hall 9. So right now i m farming up for lv 10 walls. Then, i began to realized how unbalanced and ♥♥♥♥♥♥ed the price is!!

SO LEVEL 9 WALL COST 1 MILLION PER EACH
LEVEL 10 WALL COST 3 MILLION PER EACH
LEVEL 11 WALL COST 4 MILLION PER EACH

in this case level 10 wall is 300% more gold/elixir than level 9 wall
and for level 11 wall it only cost 130% more gold/elixir than level 10 wall

how is this fair?level 11 wall only cost 130% more ?for the final upgrade??
and level 10 have to cost 300% more?

most importantly, our storages only support 8 million gold/elixir
which means only 4 pieces of level 10 walls can be done with maxed storages,
and it applied the same with level 11 wall .which is completely unbalanced!!

please lower the level 10 wall to 2 million per each, so that 8 pieces of walls can be done with maxed storages
it makes so much more sense that way!!if not level 10 walls is just basically the same price as level 11

Sorry man I don't think this is going to happen. Don't whine because things are expensive. There expensive because there good, and think about it, If you had maxed out everything in clash it wouldn't be as fun, or addictive.
