Predictability isn't necessarily bad. Just look at the Torn-T ban thread. It's established that Torn-T is EXTREMELY predictable. (Hurricane, Hurricane, Hurricane, Hurricane, Hurricane.. oh SHIT a counter --> U-Turn). HOWEVER, it's still fairly difficult to counter. Jolteon is in the same boat. What's it got for coverage? Shadow ball? HP Ice? It's PROBABLY gonna use Thunderbolt/Thunder! HOWEVER, though predictable, it's VERY effective. Let's look at Kyurem-B. Very high Atk, fairly mediocre Spe. What's it gonna do? Obviously, spam Outrage. Would you expect anything else, really? Yes, you can send a Steel type, but it's still gonna get hammered by Outrage. Ever been swept by any of these pokes? Chances are, yes. Predictable, yes. As bad as you make it out to be, no. Obviously, Thundurus-T isn't the best pokemon in the OU metagame. In most aspects, it's inferior to its Incarnate counterpart. That doesn't make it a shitmon, honestly. It has it's uses in OU, or obviously it wouldn't be here. Maybe with the advent of Gen VI, it'll drop, but as for the moment, it's a fairly good poke.
