End game thoughts
If we had carried on the game, I would have lost either by 1 KP or getting tabled as I only have 2 rhinos left while Krom have 2 devastators and a melta gunner near the 2 rhinos (1 immobilized).
I had used Mephiston in my earlier BA games and found him incredible, basically a 1 man army. Today is the 1st time I had played against him and Mephiston is really "lord of death". It is very fast and basically anything it hits dies. Truly scary and priority 1 to kill it.
