level 1~4

level 5~?？

Assign the same game group level？
group Formula？

right now with the low population on the EU servers I'd rather it get bigger than smaller. At least for the time being. Sure Lower levels will be at a gear disadvantage but that supports people leveling up instead of sliding it all to gold.

Afternoon,

I'm sorry, I'm a little confused on the wording here.
Would I be correct in assuming you're looking for the different matchmaking level brackets?

- Regards

EDIT
Notice ComptonEMT added a remark before submission:

I've gotta agree with Compton here; wider brackets will allow more players to compete.
As long as they're not ridiculously spaced -- as this would cause some serious head-smashing from higher levels on lower level players.

I want to ask threshold

If I were 11 LV ,

Was assigned to the battlefield level amplitude? MIN LV~ MAX LV ？

The brackets are static.

For example, static meaning it's always 1-4 play together, 5-9 play together, etc (these are probably incorrect)

Whereas, if what I'm gathering is what you're asking, your example would be:
Let's make x = 2, the max level allowed, so a player at level 1 could play a max n+x, n being the current level of the character.

For the minimum it's the same thing.
The game is not like that, rather the 1st example given here.

TL;DR - If you're level 11, then you play in the 10-14 bracket with the other 10-14 players (this is probably wrong, just an example), you don't play something like 9-13 (being a set number up/down from level).

EDIT - minor clarifications
