​Playing since day 1, witnessed the updates and saw what the mods try to fix. As a diehard fan of the lore and of this masterpiece of a game, this is what i believe would make this game close to perfection and satisfy all players:

Difficulty

• Every level of difficulty should only modify the number and tactics of mobs, available ammo and items.

• Mob health and damage should be the exact same across all difficulties, as they are the same mobs. Introduce stronger variants with the intent to provide stronger and more resilient enemies to spawn among the base mobs.

• Weapons need to be stronger, across the board. Difficulty should depend on the skill level to manage hordes and different more resilient enemy types, not by dealing against bullet sponges. The lore describes all weapons to be mighty, yet here they feel like nerf guns. Cannot serve him with inefficient tools.

Cosmetics

• All of them should be unlockable with a set of requirements, without time limits. On release this was the norm and it was bliss unlocking everything at our pace.

• All items should have a base version and let us customize from the ground up, no hardcoded insignias, patterns or other kind of design that might go against the desired final result. This is the first game that allows this level of customization comparable to tabletop pieces. Its almost there.

PvP

• The code deciding the grouping needs revision, its grouping up pros against low levels and results in absolute one sided destruction. It feels unfair and makes people quit PvP which is otherwise a really nice breath of fresh air from other game PvP modes with a bit of callback to glory times feeling.

Mods

• They are an attempt to fix the above points one way or another. While I think most of them go overboard, they are quite enjoyable to play with.

• I think with a touch of seriousness and lore accuracy from Saber, the game can be transformed into a gem among modern times.

These are my opinions, based on my experience as player, lore fan and witness of this sub evolution since release day.

Please share yours and if possible, organize them in a manner that if developers end up here, they can extract useable bits from it for their consideration.

The emperor protects.

Hello brother, im glad most of my argument seems agreeable upon, i feel this game is so close upon perfection small tweaking would get it into a masterpiece grade.

Regarding the difficulty topic, i mean by this to have the health and strength of every enemy to be as strong as the lore dictates from the base difficulty, simply reducing its numbers for newer brothers to engage and learn upon, while increasing the number and variance with each difficulty tier.

As an example: 

1. An easy Tyranid operation should have mostly small enemies in fewer numbers, a few warriors along the mission and maybe some raveners with the casual spores. 
2. On mid tiers it should have mostly warriors, raveners, a lot of gaunts and tolerable amount of spores. 
3. At max it should feature hordes of gaunts, platoons of warriors, raveners, lictors and the casual neurotrope here and there, with spore concentrations that need to be dealts with with skill and cunning.

In other words, difficulties should mimic the planetary invasion stages from incipient to "hours to live". In the lore these invasion final stages are described as the ground being barely visible by the amount of everything the hive mind throws at the planet.

For this to be viable, mobs need to retain their properties across all difficulties and only have their number, tactics and variances be modified while keeping our weapons equally effective across all difficulties against the exact same enemy.
