Hmmm, I imagine that the majority of folks are aware that there is X amount of time to complete an event, but human nature (in the main) is to try and complete asap.....
For the record, I'm currently in China at level 213; 214 tomorrow for sure.
I have observed some of the arguments against segmented events and what it used to be prior (I think that's the right way round).... Personally, I've not had any issue with the events, but I am drawn to state my observations of the current 'Mitchcock's Challenge' whereby a fair few number of tiles are 4800 or is it 4500??? Regardless, there are quite a number of high-value tiles, but with only 1 tile to go, I have to say that I'm disappointed with the 'returns'. Ok, I will acknowledge that the experience chests have given 2500 experience all the way thru, but at no point have they been 1,2 or 3* as on previous events... something I usually look forward to.....
