What I didn't want to tell you at that time, but now as that you cannot (or at least I hope you cannot, because I certainly can't remember) the names of the players also in that lobby, were weaker players at their kits due to skill/gear/level etc. I often carry friends because they're friends, and I want to play with them... but it would've been a bad time with that particular team composition.
Even I admit there are limits to what I can do at times. I can't quite carry everyone with level 1 on everything, and wiping is not fun for me . . . particularly with weaker teams. I knew where that team was headed, and I didn't want to go there. It would not have been fun, and it would've been a waste of time. Wiping on a level one characters with more utility would not have been a waste of time. Hunter was not the only kit you had, or could enjoy. You can present alternative options too, for example if you're particularly strong on Templar, or another. However, I don't have fun if the team is not going to do well for xyz reasons, and I try to shore up the weaknesses.
Hunter in that particular composition would've been one of them. Hunter is a solo class, and doesn't directly contribute persistent CC, or as much dps, as an archer or other class would. I've personally played it enough to see I can do well enough, but I can do so much better elsewhere.
In the case of Katari and Keeper, they're go to classes that are reccommendable at level one because they contribute consistent DPS, CC (AoE knockdown) (Static Cage Paralyze), or Barrier from level one or within seven levels (zone one or two of perilous). Since you said you had all level one's, and there was no Dragonslayer DLC at the time (I think), that's what I recommended you do.
I've got to investigate the rumour that spike trap can be laid down multiple times simultaneously. Last time I tried, this was not the case. Multiple spike traps is a big deal. Also see the other buffs myself.
Finally as to Katari wins, I already have the Katari Banner too, but he's too much fun (and effective), I can't stop playing him.
Katari is definitely great and I love playing him probably just as much as anyone who knows what he is capable of. I just didn't want to play him on that day. Keeper on the other hand, while I do admit her usefulness in a party, she just is and probably will remain the most boring class to play with for me. I think it's a combination of her ugly ass haircut and a massive inferiority/persecution complex that make her all the more annoying, both to look at and to listen to.
Yup, it was the day the new characters were released without the dragon maps and we all had downgraded stats, but that wasn't the only time you insisted I play keeper. I don't remember the names of the other two we were with, but I do remember two ladies (both using their mics), one playing a Katari, the other playing Zither and you on Avvar.
Lady Zither was doing a good enough job that having me play as keeper made little to no difference in the end. She already got us to zone three at level 1 just spamming barrier in the first round. She no longer was level 1 in the round where you had me play keeper. We still lost. My hunter was level 8, and while he's nowhere near the other great classes, I knew how to play him well enough to keep baddies away from our mobile barrier generator while she babysat the rest of us. In hindsight, we could have used a little more damage in zone 5 and less barrier because you kept charging down the stairs while you told the rest of us to use cover. We chose to protect the Katari who was doing her best to protect us instead of following the guy charging off on his own. Lady Katari, while being chased around by RTC and a ton of mobs around the walls/pillars in elven ruins eventually got overwhelmed while you got downed at the bottom of the stairs. I still don't know what you were doing there. Lady Zither and I died trying to get to you after our bodyguard got downed for the last time. We really could've used your Lady's Wrath in those tight corners, but whatever.
But like you said and what Mortiel so eloquently stated above, it's your lobby and we'll do what we find enjoyable somewhere else.
