Balancing issues

Hello, this is my first message so I wanted to say thank you for this work.
Excuse me for my english, it's not my original language, I'm french.

Thanks to you we have been able to bring out our old figurines.
A friend wanted to play Warhammer with the old rules and I did not have the courage to play it. Thanks to OPR we were able to make battles simply, without losing in pleasure.



I have questions about balancing.
In the Saurians, the Frog-mage is very expensive and has only 4+ in quality. And if we want to put it with Guardians we lose in quality for morale tests. In all the lists the main heroes have a better quality than the troops which seems logical. But not among the Saurians. A 3+ does not change much because it does not physically attack and make it more useful for morals.

In Rat-mens, I find the Grenadier too expensive. They are only 5x (12 ", A1, Poison) while for 5pts more, the Weapons-team on 3x (12", A6, AP (1)).
So 50pts for 5 shots + - 1 on average for the poison.
And 55ts for 18 shots AP1 !
Even if the Grenadiers are more numerous, by 5 they demoralize as quickly as the WPS(by3) are destroyed.

Here are some remarks I had while testing the lists. After that, there are some subtleties that I have not seen yet.
Thank you again for your incredible work !
