To be honest, they need to add a nerfed version of these events at release. Have em drop equivalent to soldiery gear or whatever the lesser tome is at the time and let folks learn mechanics that way. T5 is still to damn hard for pick up groups, T9 more so. The current nerfs to coil should be enough, it's just hard to get eight folks who know the fights well enough to dodge the insta kill mechanics. Hell, make it a token based system similar to tomes and you lose some of your final reward every time you get hit by one of the would have been one shot mechanics. Bet folks get divebombs sorted out something quick. XD

But allowing folks with less playtime or lacking statics to see content will anger the snowflakes so I dunno if SE would consider this a decent idea. Though since storyline is a big part of the carrot in this game, might have to restrict access to it to the normal raid.

Thanks for your time
