Guild Wars 2

For these influences why not just add in a number for max players presented in a guild and times that by a percentages increase in relation to biggest guild on that server.

Or just create a new resource for just for unlocking guild mission. Call it bravery point.

Just my 2 cent.

Example: 500 man guid vs 100 man guild . 500 man guild =100%, 100 man guild=500% increase and this is from highest peak of guild so they dont abuse it.

The highest guild on every server is almost certainly 500. The large guilds rarely have more than 50 members online at any time though. With your suggestion, I could make a 1 person guild and get influence equivalent to a guild with 500 members where they are all online at the same time and actively playing.

The point of influence is to reward people for playing together.
