Toning down TDs a bit is another perfectly valid option. My favourite would be some faster repair option for ost or pio crit repairs - also could do the job.
I'm inclined to disagree about fast repairs. I'm probably an hold out here but I remember a time when taking damage meant something. When retreating a tank with 1 hit of health meant that tank was out of commission for some time. When actions had meaning. When losing models left a squad weakened. When you as a commander had to decide if it was worth taking the damage knowing that the unit would be down for a bit.
I would rather see all repairs normalized DOWNWARD to EFA levels so dealing damage means something again.
Its horseshit grinding a unit down to the brink of death only to have it back in full operating order in 45 seconds. It devalues dealing damage and makes wipes too defining. It changes the game and not in a good way.
