I think that'd be part of the mech bonus. I say that because I've never seen a c-bill total above 500k; closest I've done is 430k in a hero mech.
This cockpit item + tournament bonus was a huge investment... Just look at this. Literally nothing!!!
only award items from buying ultimate clan and IS packs last year. as regards to the tournament bonus: yeah, 10% is much less than 30% and 50%. but it's global (which is the advantage over 30% from the mech) and much cheaper than premium time, as a one-time $10 investment rather than buying up to december worth of premium time. I think it's a very nicely balanced bonus. for basically donating to the 'good cause' (up for debate) of supporting your game in their e-sports endeavour.
