So. I was thinking, the two covenant fighter craft currently in the game are the T-27 Space Banshee and T-31 Seraph, in Halo lore, both are exactly that: Fighters. Neither of these craft are shown with anti-ship weaponry on board, or atleast, not enough to dent the Titanium-A plating the UNSC employ. Currently in game these two ships are employed as the fighter and bomber respectively. I personally believe that this is a misrepresentation of both vessels were an alternative exists:
Return the Seraph to the fighter role, and bring in the modified T-52 Phantom Gunboat as the Covenant bomber craft.
"WUT" I hear you cry, well, there is good reason for this. The T-27 is a poor fighter, not one to be mainly deployed en masse in battle. The T-31 as shown in the books, halo 2 and 3s cutscenes as well as (I think, off by memory :3) the visual guide: Is the Covenants main space superiority fighter.
Furthermore, the Covenant's space bomber craft could be argued to be canonically the Gunboat. During Reach's campaign (Yes I'm using Reach's story as a guide, don't judge me) when the Covenant decide that Anchor 9 doesn't need to be in one piece anymore, rather than using the T-31 to bomb the station, they instead call in X many phantom gunboats to do the job. The job of a bomber. The job of strike craft that assaults hostile vessels of a greater size.
But what about that majestic T-27 model? Well, I have three ideas in which the T-27 could be facilitated.
1. Have three main strike craft for the covenant's ships. You could have it so that the T-27 could be a lower cost fighter, but has lower health and damage to balance this (and maybe even more vessels per squadron), the T-31 could be the base fighter, with a medium: cost/damage/health(/squadron size). While the T-52 could be the base Bomber, yet with only one or two per squadron with increased health and damage per Gunboat (Because immersions 
).
2. Have the T-31 and T-52 be the main strike craft for the covenant vessels, with the T-27 relegated to planetary and shipyard based defences. A bit like the seraph for the UNSC.
3. This is my favourite idea: Have the T-31 and T-52 to be the main covenant fighter and bomber craft respectively for all of the covenant stations/ships... except the SDV Heavy Corvette. The SDV is known to have inbuilt facilities for the seraph and banshee, yet no real space in that hanger for the T-52. Furthermore, since the SDV has now become a light carrier (in my understanding), why not give it the "lighter" fighters?
TL;DR: Plz gib gunbot
