So, as of yet we only know that you can spawn your Shrike from [the] ether around you and that it's appearance is based off of your Guardian's class. Now, what if we took that a step forward.
I know tons of you want to be able to customise it, but I have another option that I'd be okay with. What if your Shrike's colours were the same as your Guardians? Maybe even its general appearance could change to look a bit more like you. I think it would be cool if that happened, but this is all just something I'd want (not confirmed or even hinted at in any way).
I got the idea when I saw the above picture and how it looked similar to the Titan driving it. It would be nice if every Titan's Shrike had a similarity to another Titan's Shrike but also have it's uniqueness.
