Not my area of expertise, as typically I use the Avatar or no TAG at all, but trying to chime in on all of these. I do own an Iguana and haven't used it for years - early 3rd edition at the latest. I remember the biggest issue was it feeling fragile as hell - 2W is much worse than 3W when its on a giant TAG chassis. So a simple fix would be to change the setup from 2 STR + 2 W to the full 3 STR. Its still pretty fragile due to being less ARM, but you actually get the chance to fix it before it pops. Otherwise, I've always liked it as a light electronic warfare TAG rather than a MBT. So could play up that angle by giving the pilot a repeater, or giving the TAG deployable repeaters or a pitcher or something similar. Surely not. The Gorgos' most defining feature has never been its third wound or its peripheral or its limited ammunition and 3rd ed basic spitfire loadout, or even its symbiomates/bombs. No, its been its inability to be repaired by anything. For it to go from that to the god of regenerating TAGs has got to be a mistake.
