Trainers as tailors seemed silly to me as well on a story level, but I understand that they were trying to add the QoL functionality without spending time on art assets that they otherwise were able to put into more important activites(Powersets, story arcs, etc).
Maybe they could have handled it with a menu option of "Oh, you're not happy with your outfit? Well, I can't help you, but I know someone over at Icon that can. Here, let me hail you a cab." Teleport to Icon.
I loved all of the travel QoL that they did. If they gave me a 0 End, 0 cooldown, instant Goto____ button/menu, I would have been one happy gamer. Travel is the biggest waste of my time, I can't stand it. I get exploration and I appreciate the effort of the artists to create a visually appealing environment, but don't force it on me when all I want to do is get to the next mission/quest. Ther are times when I have 15 minutes before work and all I want to do is one quick mission. Then, later that evening, after work, I'll slow down and enjoy the view.
I'll admit, I was probably The Guy that said, "Inherent Fitness?!?, We need this ?!?" I LIKED to have to make choices in my build, to find that balance of recharge, endurance reduction, damage and accuracy that I could sustain. I didn't mind having top slow down a little between mobs to catch my breath. Yeah, we were all SUPERheroes/villains and all of us could out perform any standard human being, but we weren't all at the same level of physical perfection. I had built my main with a slightly lower damage output per second, but his damage per endurance was sustainable virtually for ever. He couldn't take down GM's solo, and there were quite a few AV's that he trouble with, but that's what teams were for.
I was also surprised by the AoE buffs. I didn't know that we neede those either. I thought that feature was all a bout a few whiny defenders/controllers who were having trouble keeping up. I'll admit that I wasn't much of a buffer at the time, so I didn't realise the dificulties that they were having. But, I was never one of those rude consumers of buffing services that made demands on my teammates. I went into any fight expecting to do my part on my own, so buffs were an added bonus that made things easier, not a requirement to get the job done. I was always more of a DPS or debuffer. After trying out a few alts, I have to admit that the AoE feature was useful for me to buff up my teammates then get back to DPSing.
