The development group labour is very difficult
I would like to say it has been great with various new events you introduced lately and there are many rewards that we can earn and it has been fun; the spartan laours and coalition shop is one of them. However, for group labours, whilst positions and pvp labours are pretty easy to complete, the development labour is very difficult in comparison.
There are two main issues:
1. for bigger coalitions and strong players. Their cities are mostly developed or the ones left will cost a tons of sketches that they cannot immediately get. They will have hard time to contribute, which is weird as they are usually the biggest contributors in any events.
2. for weaker coaltions; they simply cannot get the quests completed.
I might be wrong but should not be far off, it requires 5210 days worth of boost to get the max rewards. That is 52 days worth of boost for each player if the coaltion has 100 members and I know not every member would participate in any coalition and we should not force them to.
I really think if the milestone for completing those tasks are adjusted to be as easy as pvp or positions labour, it will benefit every player in the game, not just for bigger guilds and we can get coaltion golds easier so we can use them in the new features you just introduced. In my case, even my guild (one of the biggest in the game) has hard time to complete the development labour because the stronger players cannot do anything.
