Can someone give me an in-depth explanation why Summoner is arguably the worst DPS?

The benefit from a 2nd super virus is usually overlooked, and I dont get why !
Plus the slow from a SMN is better.

There aren't really any uses for a second Super Virus and slow in really any encounter though.

Pretty sure that BLM gets a 40% slow too though.

Blizzard 1 gives 40% movement reduction. If you want to go further in this argument. Black Mages are superior because they also have Letargy that is a 20% movement reduction + 20% slow on skills and spells.

Black Mage has lethargy, heavy & slow at 20% for 12 seconds and 30 second cd, and I believe subject to diminishing return / immunity along with lancers' feint ability. Summoner has shadowflare, 30 second duration and idk what % slow as I think the tooltip is worded funny. Could be 5%, could be 20%. But difference also is that shadoflare deals damage whereas lethargy does not and not subject to diminishing return/ immunity.

It is only useful when the SCH dies because when you use virus, it has a 40 seconds anti body. In other words, there would have to be two moves that need to be supervirussed over a 40 second time period for the second super virus to be useful (truly useful). This isn't the case. SMN slow is inferior and also the SCH can slow .
