I have been feeling that this hero should get some QOL adjustments for a long time now as I don't feel he is in a great space right now. For me Benjamin used to be a set and forget tower when ever i don't feel like using a hero however with some of the balance patches I don't feel like he offers much in any game mode I play except on the occasional boss event where I don't use Obyn for druid farming or Geraldo for Quincy action figure. The one place I used to find Benjamin was a good choice was in co op games but with the levelling rework for him I find him borderline terrible. So i hope as least some level changes would make him better as a choice in some games.
The first and most Major QOL change should be to his level 7 trojan It should not take away money from pops. I'm not saying that it should give double the pop amount but it should give baseline the amount of money you would have gotten like Ezilis moab hex does and a bonus.
The second QOL would be to Siphon funding i think this ability has a problem where its money generating impact is hard to gage along with the fact that it is one of the few proactive hero abilitys in the game. so i think it might work better as a mass trojan ability silimar to Psi's scream where it has a chance to affect each bloon on screen. This would make it a ability that feels better to press and has noticeable impact.
another issue with ben is that some of his levels feel redundant i feel like he should gain income per round with each level
Instead of just naming some QOL i thought i would do a level rework example for fun
level 1 - 60 income gain trojan that can effect up to yellows
level 2 - 80 income Gains 5 lives per round up to base amount
level 3 - 100 income gain biohack
level 4 - 120 income Gain bank hack banks earn 5% more income
level 5 - 140 income gain 1 skimming
level 6 - 160 income tojan can now effect lead and up to zebra
level 7 - 200 income bank hack now increases max capacity by 1000
level 8 - 250 income Biohack increased duration by 3 seconds
level 9 - 300 income bank hack now increases income by 10%
level 10 - 400 income trojan now effects ceramics and gains siphon funding
level 11 - 500 income skimming increased to 2
level 12 - 650 income gain 10 lives a round and can go over by 100
level 13 - 900 income trojan now effects Moab
level 14- 1250 income Bank hank how increase capacity by 5000
level 15 - 1750 income trojan now happens faster
level 16 - 2500 income skimming increased to 3
