I was in the party, i'm guessing after the fiasco, with Kari the NIN and Precision the RNG. Im not 100% sure about how i'm stating this, but i'm very impartial because I wasnt there. But here is my 2 cents.
I joined the PT afterwads I guess, since we had the PLD and its stated that this was after the PLD joined. But to be honest, I dont think its fair to bash him w/o giving all 100% of the details. You say that Pre said the THF was never to SATA, but to my knowlege, that is not true at all. From what the PT was telling me about him/situation, he was having the THF seperate SA and TA from the incomming pull. Which to me doesnt seem like that big of a deal, I mean, sure you miss out on some DMG, but I was told how you all were working the mobs, was that he would pull, you would get TA for some hate, then a 'stand alone' TA from behind. Then about 1min irl time later, when the mob had 60-70% HP left, he would Slug-Shot then SATAVB then MB with ancient magic and the mob would be dead or super close. This is what I was told you all were doing b4 me and the PLD.
To be honest, I dont see anything wrong with that if the chain isnt suffering or no one is getting hurt. So y he was in your face or you were in his about that situation, I dont know, cuz i've been in PTs where that works just fine. Now maybe if you were really struggling with hate, SATA would be fine if hate was a problem or he was being a dumbass for spamming bullets, but no one gave me those details so for arguements sake, lets pretend you held hate fine with just TA. After reading this, I just dont feel it fair to call him names just for seperating SA and TA if you were holding hate fine and only had to for like a min anyways. But like I said, I wasnt actually there, only given details by the PT because of what just happened. I feel that if it was working, y argue.
The details about him kicking you or you leaving, I have no say on cuz I was definately there after that. Maybe if he kicked you, it makes him an ass to you, but that doesnt mean hes a crappy RNG or anything. Personally, if I was lead (being DRK i'm usually not) I would have set you up with another pt and waited for you to get one then disband you and we could go our seperate ways, because a PT just wont work right if ppl are arguing.
Also I cant justify his attitude, but maybe he was on edge because of his sister. Only about 45 min after I joined he had to leave immediately because his sister was in the hospital and he had finally gotten the OK to go see her. Prolly doesnt justify him being rude, but sometimes ppl act out of character becuase of this. I'm not saying hes not a jerk, but maybe he was just being a dick becuase of irl shit. It happens to me all the time. I'll send him a /tell and maybe this guy can at least settle this. Sorry Kari for him being a jerk, and hope your PTs are better.
But i'm a sucker to see ppl get along, cuz being a DRK i'm just so used to ripping things apart. Maybe he'll try to apologize to you, maybe not. LOL if he's blisted then we'll never know.
