This build is designed to provide medium-long range fire support. Personally, I prefer to keep my Dragon away from the front lines and engage at range as much as possible. The Dragon's natural speed should allow you to get into good positions for this, but without the higher speeds of the larger engines you probably don't want to stray too far from the pack. Depending on your preference, the AMS could be dropped for a BAP or extra AC2 ammo, or you could potentially lose a half-ton of armour as well for an SRM2. There aren't a lot of slots free for much else.
