Iíve seen these type of gaming tweaks before. Here are some examples of a League rules tried out at a local Game Store by some players:
Shield with Armor is a +2 instead of a +1 Armor Save.
The -1 penalty for 2 weapon fighting.
Heavy Armor: Change the -1M penalty to -1I
Slings: 5gc and Heroes only
(some other goofy rules I canít remember off hand)
The League was on one night a week and started with 8 members. After 3 weeks (I joined in the 4th week), there was 3 players and my self. It was my first Game, I was playing Sisters for the First strike with Steel Whips. One player, the Host showed, with his Dwarves against my Sisters. He won. The Dwarves he fielded all had Heavy or Gromil Armor, Shields, Helmets, and pistols. I ducked and weaved in and out of building to get close and avoid the Crossbows and Rifles from high up at table edge. When the Sisters got into HtH with the Dwarf ground troops. I started figuring out why the other players dropped out. The Dwarves had Armor Saves of 2+. Only 6ís to Wound (with Crits) seemed to work. Now I figured out why the other dropped out. The seemingly simple changes, changed the Game Mechanics extremely. Many other warbands became no longer competitive. The Undead player had lots of Zombies, the Dwarf Noble almost took out all them alone in the first game. The Skaven player dropped out soon after that because his Henchmen had no ranged weapons, and were destroyed because if they could hardly wound and, the Dwarf was in Knock Down, they couldnít finish him for OOA.
The next Band I was going to try these rules with against the Dwarves, was Amazons. The Claws of the Old Ones, Sun Staves, and Sun Gauntlets all ignore Armor. Iím sure the Amazons would no longer be welcome. I figured if the rules were so tweaked then the Amazons should be allowed to play. By the way the League was over before the next game.
The Moral to the story is, if you going to try tweaking the rules, you have to try them in all aspects. For and against for all Warbands. If you want increase armor bounus, play a Warband that canít have armor. If you want to reduce the Strength or Range of a weapon, play a Warband that relies on it. And one game isnít enough play the Band for about 10 games, and see if you still want it changed. See if other Warbands are still competitive, or have they been eliminated because they canít survive.
