The fact that you even talked about "smaller guilds" and "bigger guilds" already says a lot. c:

Not really convincing enough to me to be honest.
Hypothetically speaking, if a 10+ player guild vs. 20+ player guild were to clash in WoE and the latter pretty much fails to penetrate the other guild's defense, considering the SIMILAR NUMBERS of players in the guild, which or whose fault is it exactly? There are a lot of factors to be considered in this, quantity, quality, strategy, teamwork and other things. One thing is for sure for me, WoE flag-ins aren't to blame in this situation.
