I think it's the level of nuance that people are overlooking. There are so many factors going into each game.
The battle plan (which may promote having veterans or killing them)
Expert battalion for Gelato veterans counting as 3 (Keep in mind, if 4 models are left alive on an objective, they'll outnumber a unit of 10)
The BH battalion for units getting +1 damage against Gelato veterans (big damage against infantry, but not cav, heroes, or monsters)
Units choosing NOT to be in one of the two above battalions (Remember we have other battalions)
What specific battleline units are available to a faction (some will want to be geared towards one bat or the other)
The proving ground permitting only Gelato veterans to score (huge if your enemy decides to take few veterans)
A spell that reduces objective count of a unit by half (Spelldom factions get a huge benefit from this)
As is the trend, everyone will try to prophesize what the season will really amount to, but I think the game is going to be a madhouse (in a good way). Some players will skew into the damage battalion but miss out on VPs, others will swarm objectives but could get decimated halfway through. And everything in between. I simply don't see there ever being one, globalized solution to winning matches this season...there's simply too much going on here.
