I am noticing a decrease in the amount of tier 4 raids here and also a decrease in TM's. Don't know if they are touching things but I don't like it at all...If a small town gets the number of raids even more reduced then people will be less likely to play, less tier 4 raids = less players at this point because our gyms are already stagnant with this new sytem.
I will keep tracking if today the pattern is the same, raids started like 1hour ago, at the moment only 2 tier 1 around.
As for the TM's I normally got 1TM every 2/3 raids on average ( being all the raids I do tier 3 or above), yesterday I did 3 level 3 raids, no TM at all. Let's wait for more people to see how are their experience with TM's from yesterday onwards before making conclusions.
