I agree with every single thing here. Except the two handed thing. I'm not sure, it just feels off for a laser.
BOH has always been science powergamer juice. Nerfing it in this way would nerf many strategies that aren't healthy for the game. To give some examples:
- one sec officer caring and entire armoury and healing to dunk on whatever antag
- one antag carrying an entire armoury to dunk on sec
- miners carrying hundreds of eldritch bulkey swords each with the power of wizard items
- crew carrying 4000 guns to blast down a blob
I do completely agree with making AEGs bulkey. This way crew can only store one at a time in an armour slot.
Finally, I'm not convinced aeg + teleshield is all that OP. Especially once tasers are removed.
All in all, good suggestion.
