To make up for sera's having less experimentals than the other factions the Seraphim Ythotha's get the customizable keyword, and now have upgrades like a SACU turning them into a giant late game swiss army knife. Upgrades could include an experimental build suite path, potentially a RAS path, and a RAMBO Ythotha upgrade path that adds even more guns than it's already cataclysmic 3 or 4, including potentially a experimental overcharge suite, experimental regen aura, a experimental AA lightning cannon that can blap ASF's, aswell as atleast 2 more standard fairing options for enhanced damage that maybe just add a new gun, also maybe a shield upgrade potentially... details pending, it'd take time to work it out obviously.. maybe a unique upgrade that enhances the ion storm too? no tele though... as cheeky as teleporting a upgraded Ythotha into a your opponents T3 artillery battery would be, it would be extremely rage inducing and not at all fun for anyone besides the sera player, lol. In general I like this idea because it takes what seems like on its surface the most disposable of all of the T4's, in a faction that is short on T4's and fills it with depth. Other factions get more experimentals than the seraphim, so it would only seem fair to go ahead and give the seraphim a few more fun late game experimental options.
