Actually, it doesn't imply that at all. Maybe you're familiar with Allakazham's FFXI forums? Or perhaps one of the other multitude of FFXI forums where people reinforce FFXI's unwritten rules? Every day it seems, a new summoner, or a disgruntled old one comes on and rants how summoners shouldn't be main healers. Summoners should summon, they say. And every time this happens, a whole bunch of people with nothing better to do, say: "So what're you going to do for the 60 seconds between BPs? Melee Lolsmn? Nuke w/ ur blm sub for 3 dmg? Ur a gimp". I'm not making this up. I was just making fun of it in my thread title because I read FFXI forums WAY too much. Anway, it needn't have been an issue regardless. I dislike the FFXI community in regards to how anal it gets about perfection. Way too many rules. I make cynical comments about it whenever I get the opportunity. I could've just kept the title informative, but it makes less of a point.
The topic title means: The community will have to adjust their excuse for pidgeonholing summoners in a role many dislike. SE adjusted said excuse by ~30 seconds, letting smn's BP 2x a minute.
