If that's true, then the ability is essentially worthless, and will get worse as each new renew haste breakpoint is reached. It's pretty much not worth casting at all once you hit 4254 haste for glyphed renew, and 12612 haste for unglyphed renew.
It's questionable for the 3039 unglyphed renew breakpoint, due to the movement advantage of renew, as well as the ability to do the healing incrementally without potentially delaying plague/mind blast/FDCL procs (or in the case of healing, to avoid delaying PoM or your level 90 talent spell).
I'll double check on the hymn ticks when I'm able to respec holy after my raid.
Edit: Hymn of Hope definitely does not gain extra ticks from haste. I haven't respec'd holy to double check DH yet, but I assume it's the same.
Perhaps it's not technically a bug that symbiosis tranq does not receive extra ticks from haste, but it's certainly true that it's awful and pretty much useless.
