I'm currently facing two challenges for both the Grot Rebels and Thousand Sons and would appreciate some suggestions on them...
Problem 1: What to do with the Dakka Tanks?
For my Hydra tanks in the last codex I converted these small support tanks adding a carriage at the back to keep the armour facing correct, I had planned to use them for my Wyverns but I fear their size could be a problem. See the Hydras never benefited from their small size as they were always in line of sight so they could have a wide range of targets, the wyvern being a barrage tank will often be behind terrain so I fear it's size may become an unfair advantage.
So now I'm wondering what to do with my 3 small tanks because I really don't want to ditch them cause they look awesome, I was thinking of using them as FW immobile weapon platforms but then someone suggested using them as a squadron of armoured sentinels since their base size is 60mm square. It's a tempting idea since all I need to do is remove the heavy bolter and add a big turret on the top for the main weapon, as for the close combat stats maybe a tank commander with a powerfist or something?
I dug up this image from the previous log for a side by side comparison.
Problem 2: Pre-Heresy Scouts?
Once I'm finished with the grots I'm likely to start work on a allied attachment of Space Marines for my Grey Knights so that my pre-heresy Thousand Sons can field an actual Contemptor dreadnought and legion battle tank. The best choice for the required Troop slot is a scout sniper squad, the problem thou is that Scout squads weren't present during the great crusade instead they had recon squads but I'm not keen on the idea of just having Maximius armour representing 4+ armour.
So I'm trying to think of a way to convert the armour to look less like a standard space marine? So far the best idea I've had is using scout torsos with Maximius armour legs.
Your thoughts on these two topics?
