Timery jako prawdziwa waluta
Nothing in this game is gated behind skill for very long. It is gated behind time, in the form of an upgrade queue that runs whether you are playing or not, with heroes as the longest line in it. That is why listings in Clash of Clans accounts are priced on hero levels rather than on town hall alone.
It also explains why a rushed village is a problem rather than a shortcut. A high town hall with an unfinished lab is matched against opponents built for that level, and the attacks it can field do not keep up. Fixing that order of upgrades is the most common request in a Clash of Clans boosting order on an existing base.
The decision is really between waiting out the queue and buying past it. Either way the payment is protected by the escrow described in the Eloboost24 buying guide.
