We had a pretty long discussion regarding the utility and necessity of adding shields to heavies.
Utility wise. The shields sound like a good addition but it would then devalue Doom's Unit use in combat and as a battalion. On the server back-end, we'd prefer not to add more spawn-able entities to jobs than we already have. More entities = less stability especially during events.
Necessity wise. We don't really see a need for shields on the job as this could potentially lead us down a rabbit hole of other jobs "Needing" something special to stand out when the jobs already have load-outs and models to make them stand out and perform accordingly. There's also another suggestion up where I will be taking another look into the rotary blasters and adjusting where necessary, providing that post actually receives feedback.
For the future of Heavy suggestions moving forward; There's always cool ideas on how to improve a regiment, but pulling directly from another source of specialty on the server will only deem to hurt both sides in the long run.
