I afraid that you misunderstood Frontline fundamentally in this case.
TLDR, what I am about to say has no ill attention or on purposely trash EN/EU community as whole.
There is always a misconception about Frontline from EN/EU community, people in general thinks it is just a copy of WoW's Player vs Player battleground.
The truth is Frontline is a variation of MOBA, a subgenre of real time action strategy game.
It is somewhere between Action game and SLG game.
There are 3 teams in total and each team has 24 resources and each resource is control by one player.
The key to win a frontline is how to adopt to situation created by RNG in real time and manage your limited 24 resources.
Drones and Ice have their meaning in Secure and Shattered and it works the same way as towers in MOBA.
Many of MOBA terminology can be apply to Frontline.
For examples:
High Battle High players are ADC, they are usually veterans becomes formidable at end game and deal most of damage to enemy players.
Normal players are Pushers, they are primary responsible of fulfill objective (such as Ice and Drone) and following ADC's kill sign.
The use of terrain is also a key in Frontline like every other SLG game; however, most EU/NA players choose to push through with brute force instead of using terrain wisely.
Considering all Frontline maps terrain are well designed and each fighting node will always have two exits
Frontline is widely accepted as SLG game by JP/KO/CN and there is the main reason why you are always seeing someone taking the mantle of "commander" or "shot caller"
This person will be primary in charge of how to use this 24 resources.
In general, they will have much better Frontline experience because general players over there knew they are playing a strategy game.
When it comes to EN/EU, due to people's misunderstood of Frontline resulting to bad Frontline experience and this is why you are seeing other thread asking to delete Frontline.
Every said in that thread just showing how deep they do not understand.
