I know it's time consuming to get multiple characters through your daily routines, and I know sometimes it's more of a pain to offer assistance to others, but if you know your stuff, it would be greatly helpful to the game, in general, to offer to help unknowing people with their skill. I ran a t9 raid yesterday with a pug group. The tank was Rage, and I could see he was in obvious need of a mentor. The powers he was using to tank, were not meant for tank. So, after we failed, and failed, finally succeeding, I offered to help with a more suitable tank loadout, to which the person was quite happy to receive. It took about 15 minutes to respec, allocate skill points, give a loadout, help with rotation, and give examples of how to tank; as well as put on track with artifact priority. Now the next time he goes into a raid as a tank, he won't die on the first set of adds, and will likely survive the bosses now. His cr was 288. It takes just a short bit to help someone, rather than get agitated and leave them stranded with no help.
