Yes some of the upgrades can be unseemingly too long.

Are you playing singly or part of a clan?

There are strategies that with patience you can cut the times way down, and save yourself a lot of boosts in the long term.

Love this game but however...the upgrades are ridiculously too long....I am on disability and don't have alot of money to keep purchasing boosts. No way I can even compete with higher level players if I can't upgrade quicker...I mean come on...17 week upgrade...no upgrade should take any longer than 3 weeks...TY for your time

Unfortunately upgrades are much longer on higher game levels (i.e. troop health 3 lvl 15 it's 12800 days = 35 years without reducers). I would join strong clan, participate in events as much as you can, get gold and boosters rewards. And you need to work on hero stronghold gear - start with learning and building one. There's plenty guides online - on this forum, youtube, other websites. PM me if you need more details.
