"Alte Hasen" really need a buff

Hallo Wikingers,
I tried GD-Pz.Gren “Alte Hasen” to kill enemy’s heavy/expensive tanks serveral times and I works when you use the elite unit to ambush them.
But the poisoned grenade harm my own unit too when i must approach near the tank in order to throw it. Their combat ability is bad too, equal to a regular pz.gren with full upgrade, cause if they losed in number they lost a lot of power.
In gerneral, I think “Alte Hasen” mounting on a panzer 4 is not worth 800 MP right now.
Some suggestions to solve the problems:
1. The range of throwing anti-tank mine should increase

2. Their weapon should be: x1 LMG42, x3 STG44, x1 PPSH and  x1 panzerchreck (the chreck should be pull out when vehicle approach, if there is no vehicle nearby, that member will use a MP40 or a pistol)  – I think to replace a ppsh with a STG44 will help a lots for the combat power.
3. Give them panzerfasut 100 or regular smoke grenade. (for if you want to use them as a frontial combat troops)
After a lot of games, I think GD-PzGren right now is not worthy the price (5 CPs and 800MP), and the GD-Pioneer branch is a lots better.
