I'm up to 3039 in my campaign, 15 'mechs short and still only found the one hero (Highlander).

Anyone know when the rest of the new 'mechs start appearing in stores?

Supposedly there's an error with their spawn weights
Generally they should be starting to show up post 3025.

I've seen the regular melee variants show up since I started the campaign.

But the hero 'mechs don't seem to appear until the late 30's (Highlander) and then '42 or '43 (Hatchetman and Quickdraw). Still haven't seen the other two...

I had the hero Quickdraw show up right after the kestrel lancers campaign, so at least as early as 3030.

Huh. Guess I'm just unlucky :)
