The Black Mage destroys the Summoner in every area single target, aoe, survivability and utility. Black Mage's also have a soft DPS cap so they can easily exceed DPS checks with the minimum amount of gear while the Summoner can't they have to over gear endgame raids to viable. Despite what many people think Black Mage is sustained damage all of their spells hit instantly and they are able to maintain their damage around their maximum. Summoner's are spike damage there DPS starts high then after 4min their DPS rapidly declines because they instantly lose 27% of their dps for 60s since they have no Aetherflow stacks, Shadow Flare is a waste of mp to cast and enkindle is on an ungodly long 300s cool down for a move that contributes to 2% of our total DPS. Even with all of our DoTs ticking which is 35% of our Dps with the pet doing around 28% and ruin spam 10% anyone can plainly see during the phase in which Summoner's are out of Aetherflow stacks we lose 27 - 30% of our DPS for a minute which is 8100 damage if they do around 450 DPS and 40,500 damage over the course of a 10 min fight. That is if a Summoner plays perfectly if the Summoner is good or average they can easily lose 60,000 damage over a 10 min fight which lose of 100 DPS that is the issue with Summoner players are punished for playing perfectly and brutally punished for being good or average.
