Changes that should be made

There are times when I get attacked and the enemy steals around 1300 dark elixir, if u ask me thats way too much and it should be changed so that the enemy can steal a max of 400 and listen why, at the beginning after I got my lvl 9 town hall and finally got a second dark elixir drill I could only manage to get a max of 240 dark elixir every 6 hours, now after spending many hours and 10 mil of elixir to upgrade both my dark elixir drills I could make only 900 every 10 hours (one of my drills is still upgrading) so per night I make 900 (not yet) but the enemy steals 1300, thats a 400 loss (cannot make progress and its frustrating even after all the upgrades). Another thing that should be changed is the research for all the troops should be better, like the 6th research should at least upgrade at least twice what the 1st research did for all the elixir I am paying to upgrade (for example the 6th research which is the highest research for the barbarians should make their lives 150 since the strongest defense buildings do 75 damage that way it still a kill in 2 hits and for the people that got that high up for their research it finally shows the difference for a lvl 6 barbarian compared to a lvl 1, its more fair that way). Another thing, the dark elixir drill should be upgraded by 20s for the output that way the cost for the upgrade is fair (for example, by the time I upgrade it to level 6 I should get 120 not 100 like its now). Another thing is the walls are getting too expensive (for example a lvl 6 wall is 75,000, a lvl 7 is 200,000 and a lvl 8 is 500,000, thats too much, the way I think it should be since a lvl 5 wall was 30,000 which seems to be fair enough cause if u add it up when u are paying for 250 walls that adds up to 7,500,000, now don't get me started to the higher lvl walls its way too much, and the way it should be: lvl 6 wall should be 60,000, lvl 7 wall should be 100,000, lvl 8 wall should be 200,000, lvl 9 wall should be 300,000 and lvl 10 wall should be 400,000 even like this its a lot to pay but at least its better). Another thing that should be changed is the power of the x-bow, for 6 mil I expect at least an extra 50 damage (right now I would only get an extra 10 damage, now that is pathetic for the strongest defense weapon). Another thing is the idea of paying to view clans after I press on attack is that it costs too much, right now it costs 750 for each view (I recently spent 70,000 just looking for a clan to attack, that is too much, it should be changed so there is a max of 250 per view that way people won't lose money just for looking to attack another clan).Thank you to all that read this far and please rate.

Well maybe instead of collecting de, focus on upgrading all your defenses and walls to max? Then you would have a fair chance of keeping a consistent amount of it. Walls are perfect the way they are. You should have them over lvl 6 if your a town hall 9......
