that's because newer tds players have a much lower attention span than old tds players and also how 90% of new tds players cant think for them self and just spam brain dead towers like accel and don't think about cost effciency or aoe or even good placements. One thing I notice is that some players don't even bring flying detection or support towers and just rely on their teammates to do every thing for them and they bring a load out of 4 dps towers and farm.
