For Glykhan:
1. You need mutants with prowess, i recommend Bishop, Both Storm and Emma. I used Storm Pyramid X as i didn't have OG.
2. Domino also works. She can fail root in phase 3 due to AA reduction at times which is helpful. It happened for me 40% of times with the 3 path attempts.
3. In MCoC Noob Video, he didn't recommend Gamora but that's not true. I watched Jason Voorhees video, and got inspired to use my fav Gamora. She hits like a truck here, i almost soloed with her.
4. As per Jason Voorhees we need to keep it simple, it's an easy boss. And they are right. Ignore all judgement icons. In phase 1 and phase 2, just dex specials and punish it with heavy, stun, special chains. For special 1 rush in after kickback and For sp2 rush in after Axe throw. That's it. You will not have any issues dexing specials and heavies in both phase. Once you have practice, these phases will go smooth.
5. In phase 3, you can go in with good health, don't be shy to block special hits and dex and punish only the last special hit, that's enough. Degen won't do much damage and your champ will do a lot damage.
6. In phase 1, build till sp1 of Glykhan's power and dex & punish specials and heavies. You can build till sp2 as well and do same, no issues. In phase 2 you need to build till sp2 of Glykhan's power only and he chooses a special randomly. Now continue dexing and punishing either. For phase 3 you can build till sp1 preferably. Glykhan roots you on specials. To make it easier follow point 5.
7. All 3 paths don't make any visible changes to fight. It's as simple as dex and punish special specials and heavies every time.
8. For last 1%, you need to be a mixture of agressive and passive, you don't want the rooted heavies when completely passive. Engage Glykhan in 2nd half of indestructible timer with relics and combos. In this phase take only 1-2 specials from Glykhan. Ideally 1 to start the indestructible and one just after it ends. This phase needs a bit luck but you will do it eventually.

Overall it's an easy and fun boss. He fits in accordance to rest of Act 8 bosses and Kudos to kabam for making him fun. It's great that none of the minion bosses or paths were tough as well and good that they didn't introduce any new recent defenders in 8.4.
