This new event is joke of the game. Not it only drains all yours resources and the requirements are also fk joke.
Clearing rubbles are in a mess and make no sense at all.
ex:

- Heroes with Wizards mercs. AC/Imp with Witches counts as Wizards. But Enchantress with Witch doesnt county as wizards mercs?
- Heroes races. Rath count as Human hero, really? Same as others heroes doesnt look much as human but as well count as human hero!
- Require 5 heroes with Ox Warriors mercs. How many epics heroes have Ox as mercs? 3!

and the list can go on.....

Already mentions. Guild Mall 25k gold twice a day drains the gold faster than guild can obtain. 

Improvements:

- More gold to have at least a chance to gain gold for base upgrades without draining all resources. Clearing rubble/Daily sign ins/conribute/buy gold from guild mall. All should give more gold. Or lower guild mall gold stupid change 2x day.
- Change rubbles every day. Some rubbles none in a none/less spending guild can clear is a joke and it just stacked up until no one can clear any rubble or want to waste resources for crap 5000/10000 gold. Which arent even enough to maintain 50K gold/day guild mall robbed. Enlightment/insight are hardest and none spending guild can ever clear.
- Guild mate can help with clearing rubbles and not just alone.

Sure its more crap that it needs more improvement.
