is blissey now almost worthless?

for me there seem to be three lots of gyms

1) stable - an out of the way gym that was your real prize under the old system, I put my blissey in there on day one of new system when it was going to take 5 days to get coins and do not know if i will ever see it again.

2) high traffic - it's going to get turfed anyway usually before you collect. someone may feed it a berry (for the time being) to try and get candy but it's still going.

3) gyms held by people slow to realize that sit and collect doesn't work (who will still retake a gym the moment it changes hands discouraging turnover)

except for type 3 Blissey is either unhelpful or actually counter productive.

the main thing to invest in now (lucky I have been 50:50 on my attack/defense) are an efficient stable of attackers for raids and to make the odd gym attack more efficient.
