He should not be in the Freiljord training his bear people to be ready to defeat that evil force? why is he wasting his time in the league of legends?

Because he felt like it

To defy the Time Lord of course.

imagine a bear army dude

Isn't the League a way for nations to represent and defend themselves against other nations? I wouldn't imagine a tribe would be too different than a nation in this case.

I'm pretty sure he did it to show his tribe that even a time lord couldn't stop him.

Sounds like a Zileas smurf to me

By the new lore? It seems like nobody is actually 'in' any sort of league. They're all just characters in a story that we're allowed to play as in a completely separate 'league', instead of characters in a story whose battles we play out.

I shudder at the thought of "Bear People"
