Then the firing speed could be changed to 4 sec or the bio effect could be reduced to 50%-60%. I would prefer to change the firing speed. And heat shouldn't be important for this weapon. We have already the HE CN, which is only usable with coolant engine. The addition in gameplay would just be, that BE could use Bio. And for me physics and electrical are ok for both sides. Physics: 3slot ML and good 2slot Cannon Electrical: 3slot Cannon and good 2slot Missiles Only little problem is, that HIT missiles have the same effectiveness for both sides while rail guns are better for BE. But this should be discussed in another thread. And I see that some of you want to redesign the complete research tree. I say this will be no problem if we have regularly test sessions with 20-30 testers to balance this. But with the current tests we can't do any big balance changes.
