The way balance is gauged is actually pretty involved, and includes the use of extensive, sophisticated software telemetry tools that can provide a spectacular amount of data for analysis.
The data is then filtered to allow the developers to determine how many times someone gets killed by a weapon and they rage then that one needs nerfed. That is the forum balance on weapons.
If we look at balancing in the smallest squad based model currently its at least a happy medium between 1v1 and operating in groups of 5. 3v3 is probably the best way to approach this topic I think. So choosing the arena is probably the best choice but not limited to opr and territory wars because there is enough of a blind spot between weapon selections when building a squad to think tactically. You are given 30 at least seconds to switch weapons for whats in your inventory to change your build into what ever you like and revise your personal stats. Which is more than enough time to do all of that if your paying attention. So entering in with only one set of armor and one weapon build is akin to eating an entire tube of glue stick only forgivable upon one’s first three matches before someone should probably talk to you about tactical team building.
A well balanced team would nominally have a healer, a dps and a tank with no real focus on specializing in anything particular.
An aggressive team would have a tank and two dps
And a defensive team would have a healer and two dps.
A hyper aggressive team would have all dps and would be vulnerable to aoe builds.
A hyper defensive team would have all tanks and vulnerable to fast dps types
And a turtle team would have tanky healers. Which is absolutely vulnerable to ranger types.
Its up to the group to decide which way you want to play but none of which are bad tactics.
The only model that stands out in the game is 1v1 but even so you can essentially play rock paper scissors with weapons that synergize with the armor you wear. To play a juxtoposing effect on the build to fight on equal terms with a player that also has a mix build. Switching off from one weapon to make use of the special attacks but the light and heavy attacks are absolutely essential for 1v1 in terms of gaining an upper hand. And people fail or refuse to see that value.
In plain terms, if your trying to fight a dps choose something equally fast or absolutely defensive like sword and tower shield or a good crowd controller like the spear and if they choose to switch to healer, then you switch to something thats good against the healer. Im a healer and I cant fight against a ranger type so i would suggest a blunderbus, bow or musket not a fire staff though thats not a good way fight a healer.
I applaud people for wanting to stay with their favorite weapons but hope they understand that they will fight a mostly an up hill battle.
