IS Pugs, plus the rewards benefits for Clans, plus the small gap in advantage for Clans tech (not huge, but it's there), plus the Cbill payout for Clan merc contracts, equals a heavily stacked clan side right now. As said before, the tonnage only removes some armor from the field, but doesn't level it, and in the case of the complex but obvious gap between top-line Clan units versus IS units, it will only speed up the clan stomping process.

I am not whining for the sake of whining, I am just pointing out the flaws and it's not an easy fix. Right now, if anything, I would drop the Cbill % payout greatly for all Clan contracts, and up some of the IS contract payouts. I wouldn't touch tech (it's supposed to be slightly balanced against IS anyways in lore until I think about what, 3065-ish? Haven't read that far in the books. I would also maybe add a new faction or two to the IS side, to offer the rewards and mech bays that current top tier units who switched to clan for those. Maybe Arc Royal Defense corridor, or something from the Chaos March, or even the Canopus Confederation (might have that wrong, but the one in the periphery). Something to attract top tier units back to IS side.
I don't blame the players/units who want to go after the rewards and benefits, that's a game design thing and it's natural to chase it. I do get salty when I am getting stomped, but again, the game is currently tilted to created the conditions for said stompings unless you are dropping in a 12-man IS premade yourself. Unfrotunately, right now because of the current state of where top tier teams are aligned (all or mostly clan in top 20, regardless of Merc or Loyalist) there is not a lot of chances to be lucky and dropped with a good IS team.
One thing that could help is getting the TS3 and Discord Hubs advertised, that would help a little with organization and getting premades going.
Anyways, the point is adjusting the tonnage at this time will only exacerbate the 'market' problem in the game right now. Fix the Rewards, increase IS CBill payouts and reduce Clan contract payouts, and finally add another faction or 2 for IS side to work towards and attract the top-line units back to IS side to balance the skill distribution between IS and clans. Then you can tinker with tonnage.
