I think this game has a habit of offering what people want (i.e.whats relevant to end game) with only the new content, but not the existing content. The old content remains unaffected, which means it becomes irrelevant for EG purposes. Underground is a good example. I enjoyed this DLC so much at release of the DLC, but it become irrelevant to EG with future patches. Which makes it pointless and hard to group (since it is pointless EG content for others as well). And "hard to group" is a true killer. If it really isn't worthwhile solo, content-wise.
So, Resistance is where the Classie is at. Everything else is practically not. DZ remains the even ground, and UG has been brought up, but rest of the game...
In 1.8, they finally brought Underground up to the meaningful EG drops . For a while UG languished with irrelevant drops for EG. This has been corrected. LZ and HVT needs o be address and not left to languish as it has been. I guess HVT could be decided just something that "non EGamers" use to get there leg up. Fair enough, however, non DZers need a chance at Classie and DivTech. So why not allow HVT a chance to play a part in that balance.
Just a Note: I keep hearing that bosses (DZ,LZ,HVT,SupplyDrops) all have a chance of Classie drops. However my experience and what I read, LZ and HVT never have that . (HVT is know for EIR and HILRD drops, like LZ has ShortBow,Caduceus,Tenebrae). So, it seems bumpkin.
I think that HVT and LZ need to also be brought up to what is relevant for EG.
So , yeah, provide DivTech for LZ et.al.
I think Legendaries and Heroics already have DivTech which can't be over farmed since they come from once a week Exotics. So allowing LZ to be moderately farmed for DivTech provides a balance. So, leave that as it is. Let LZ and HVTadd to pve player's access to DivTech.
UG offers Hunters as access to Classie. So really HVT could do the same thing. When you accept a he more difficult top tier HVT, you run the chance of having Hunters try to intervene. Effectively means more challenge with more rewards.
DZ is already good for DivTech. Mobs drop DivTec as well, so there is more that what it seems.
Another Note: During the GE4 the drop rate seemed fantastic, though afterwards it has been a desert. RNG is hard to guess but reading others comments I suspect variances in the drop rate between GE and now
