Well, I decided to look into this more in depthly. The highlight of what I found is, it is literally impossible even with a max neck of 471 to reach 380 ilvl average with only full 378s due to the trinket slot, you are correct that it definitely is what drops your ilvl by a lot. However, as you get more 388s the easier it gets, just one 388 makes it possible at 471. With full 388s including the trinket 388, you only need a Heart ilvl of 348. If you don't have access to the trinket, its still possible, but becomes a lot more difficult requiring a 421 Heart. The Heart as per usual is pretty important on this, whatever ilvl you don't get on other gear you can get absorbed up to a limit of 471(might be like around 425 for 119s though. Eventually becomes very difficult though to get a new level). I believe level 50 lies around Heart ilvl 378 as a baseline, but i'm not sure. But basically my suggestion is, get your Heart level as high as possible on your best 388 chance character so maybe hopefully we can access this, It seems very unlikely but you never know! Casters with access have the major advantage with the trinket, I see them making it into the raid above any others if its possible with the chances we get.
