@bboyvince, unfortunately if you read that entire thread (and don’t  it’s long and there’s very little point) you’ll find that MAGS came in saying they had received responses that gave no satisfaction and seemed final.
It seems pretty clear to me that you should go ahead and combine them. Here’s my logic:

When you started the Alkashard farming process you knew the reward was 50 emblems, so you already decided this is a good enough deal.

Your speculation about the rewards increasing should include some probabilities. Let’s say there’s a 10% chance the reward increases to 100. So there’d be a 90% chance of 50 emblems and a 10% chance of 100. That’s an expected value of 55 emblems. How long do you think it’d take for that improvement to roll out? It’s not being discussed for V28, so a month or two at the absolute best? Would you rather have 50 emblems now or 55 a month or two from now? You can plug in different variables if you want, but the process is the same. Talking about 100 emblems is misguided  you need to address it in probabilistic terms.

When choosing variables in that equation I was pretty generous about increased rewards (in terms of amount AND likelihood) and timing. I think the chances the rewards are improved is far less than 10%. SGG has had plenty of time to change the Alchemy Lab, yet they’ve done nothing about it. This is the case despite it being widely panned. It is pretty clear where their energies are focused from reading the Beta Beat threads. So even if the AL is on the list I think the time frame is long.

Lastly, if the Alkashard rewards are changed there is at least some chance they will retroactively give rewards. I don’t think this chance is huge, but I don’t know that it’s less than the chances they change the reward structure at all. And if it’s nonzero that is yet one more variable in the EV equation that should incline you towards combining now.
It feels like you’re trying to maximize rather than satisfize, which is fine  I’m the same way, so understand that I’m not offering this as a criticism so much as the best analysis I am capable of. If you were a satisfizer you’d go ahead since, as I pointed out, you decided 50 emblems was enough to start farming Alkashards.
But even if you’re an optimizer, the best case isn’t that you hold out, get the timing right, the rewards increase, and you get them (as you imply). It’s that you combine now, the rewards increase, and SGG retroactively gives you those additional rewards, with you having gotten the usage of the original 50 emblems during the interim.
