Some try to use the word "prepare" to cover the fact "exploit/cheat".
Let say we have a foot race, some people prepare like tomorrow will have a rain, so they wear boots to run faster, it's fine, good prepare. A few guys prepare ... a helicopter to take them directly to the destination. Basically there is no foot race, when some people don't run by foot, there will have no foot race anymore, no competition, everything fails.
What is Lilith's purpose to hold a powerfight event ? If they just want to give out some linari, chests ... just give it now, no need to hold a 3 days event, there are no competition, the winners are already at their positions right now, the rest will get some useless chests, some woods, golds, etc.
