There is always a reason. I'd expect its either:
1. they can't be bothered
2. they have so little staff they can't do much
3. they don't have a clue how to
4. they're too busy fixing the good things (uprise, royals etc) although they've fixed most of those now.
Personally I think its number 3, particularly because of their help center replies...if they knew what they were doing they would give a good answer. Since they don't have a clue, the help center tickets build up so much that some don't get answered, and the rest get a 'I'll send it to the techs' or 'it's your fault' reply.
They said they would fix WRs months ago, which further supports #3
However I wouldn't be surprised if all my reasons play a part (maybe not #4 anymore), like asking for loads of screenshots as they can't be bothered to find the people who used troop glitch for themselves and can't be bothered to find each and every player who used the glitch since so many used it, plus those who used it spend tonnes; and since Dawnseeker left, I wouldn't be surprised if that isn't becoming widespread since I bet staff are getting fed up with all the complaints and abuse they get haha
Endless complaining won't fix it, but they need a few so they have a slightly bigger chance of fixing

The problem is, the players who play seem to know more about computing than Evony staff, so really they don't have a chance
