Hoarding tokens for three months seems excessive, especially if you are pretty new to the game.
You may not want Aegir now, but let me point out that as current hotm, he is relatively easy to get, and if he comes back as one of the special Atlantis 5* heroes in six months, he will be far less likely to get then, if you later decide you want him.
Please note that in this game, heroes are often adjusted either up or down because they are overpowered, or underpowered. So he may become more useful. Or popular opinion on how useful he is and what to do with him may shift. Ex: Gravemaker on initial release got very mixed reviews with lots of people thinking he was underwhelming. That has clearly changed, and he hasn’t been buffed at all.
Besides, when you use your tokens, you will mostly get normal 3*, 4*, or 5* heroes. If you don’t want/need them, they are food for the heroes you do want.
Burn em if you got em.
And if you really don’t like Aegir, wait 'till November 1st, and you will have a small chance at the next hotm instead.
