Okay, my honest opinion is that you see this kind of match all the time, the large brute vs the agile hero. The hero always wins. Plus which thrall are you using? in WarCraft III his powers are, chain lighining, spirit wolves, far sight, earthquake. But if your using the WoW version, Link may well get stomped, considering his powers are of a larger range and greater power.
Anyway, enough babble, Link would cream Thrall, he's killed the kind of creautres that legions of orcs and shamans have died against, dragons, giants, demons etc Considering your boasts on thralls power, which is bull, i'm a hardcore WC player, and thralls not as powerful as your making him out to be. Link would still beat Thrall quite comfortably.
What i said earlier, Ganondorf actual power, is stronger than thralls, so it makes sense Link can beat Thrall
If you want to use the warcraft universe may i suggest:
Link vs Terron Gornfiend
Link has the skill, Teron has the power, only alot more of it than Ganondorf.... Infact i'm making a thread
