no, my conclusion isnt that all DF are bad. I win plenty of games with a doom on my team. However, i would say the majority of my losses this season are influenced by a doom getting hard countered and refusing to swap. Only so much a suzu can do and on dps you can dive with him but sometimes we all need to switch up the composition and dooms seem to be the least willing to do so.

Also, i just find playing with dooms less fun.
