But you are forcing me to choose between 1 or 2 Commanders. Command P4 is not a stock unit.
(If we exclude Festung Armor) I count 4 very viable, and varied commanders that have the Command P4 option. Each of those 4 commanders has other abilities that synergise really well with the P4 (e.g., Elefant, Spotting Scopes, CAS, or Ostruppen for, effectively, 7.5-man squads).
If you have issues vs Allied rocket artillery, you are probably playing team-games. Since you are playing team-games only one player actually has to pick the P4 (and the rest of the team can benefit).
Yes, it's limiting. Yes, it's a desperation option. However, it is still an option and I (personally) find it to work really, really, well for the harsh realities of team-games.
However, if you sit down and weight the options, the only heavyweight OST tools you are missing out by picking a command P4 commander are:
- Stuka Dive Bomb (which is ridiculously OP and is long due a reversal of the ninja-buff)
- Tiger (which you don't require in a team-game, since KT is always better)
