I love the WH40k universe and i love Arpgs, Martyr is a great game , but i have some suggestions to make it better. After playing thousands of hours in Arpgs i hope i can give you some good ideas what to implement. And im so glad to see the game still getting content with seasons.
-Training dummies, on your ship have a teleport that lets you go to a training room. Having different kinds of training dummies or by the player adjustable dummies. For example a group of 3 or 4 dummies that dont die, 4 dummies who do die and respawn instantly to stack tokens, a single target dummy, a boss dummy, a single target dummy which attacks you back so you can stack berserk token, 4 dummies that attack you back so you can stack tokens and try AoE builds.
Having 4 dummies , a boss dummy , and a single dummy, and a terminal to change their behaviour , like life points , being hostile , being passive, their damage ect. would be great
-Cosmetics, I know its not lore friendly but make at Omicron Arkh under appearances a Transmog tab. Then let us transmog into enemy units like Chaos Marines , Plague Marines, Chaos Daemon, Dark Eldar ect. The skins look amazing and are already in the game, maybe make them unlock like killing 500 plague marines you unlock the armor skin. If this isnt possible because animations , maybe give each class more skins, armor appearance variety , or cosmetics like holsters, bandoliers, skulls, badges ect. fitting for WH40k. I would even pay money for those skins and it might be a good way to support the longevity of the game.
-The damage/difficulty scaling. I know it might be too late. But you know every other Arpgs does it the opposite. Your damage numbers stay the same but enemy health scales higher. Not -99% damage dealt. It feels very disheartening seeing those big crits when you play a mission on your level and then those little numbers one higher ones. It makes me and others feel getting weaker.
-New weapons for example, Eldar D-Weapons, Dark Eldar Dark matter weapons, Lightning Claws, Chains fists, Neuro Gauntlets, C'tan phase weapons, power fists ect.
Especially the Claws would be awesome for melee Crusader, and they also exist already on those Chaos marine enemies. Neuro gauntlets would be a similar good choice for melee assassins.
-Relic beams, give Relics a colored beam , red , orange ect. like diablo does, i miss relics regularly because of the amount of other items dropping
-New enemy types/variety
-More Maps and variety, and it would be amazing to see a map editor where the community can create and upload maps for everyone to play, in recent years ive seen several games who gave this option and the community maps are amazing and fun to play and give countless of hours for people to play. It could be a seperate mode to play custom maps, where you go into mission deployment, and have a 3rd tab which is called customs maps.
-Companions, give them the function to pick up money and resources so you dont have to do it yourself and they serve a real function
-Reroll Enchants, give us a list at the right side of the Reroll tab so we know what stats can roll from each item and stat. So if you click on for example +15% critical damage bonus there will pop up a list to the right that shows what stats can roll instead. At the moment its not only a gamble but people dont even know what stats and effects can roll if they press Reroll.
-Endgame progression. I think a paragon/prestige level system would be nice, where you can level a seperate level up system after you've reached level 100. You could for example give cooldown reduc, Dot damage, crit damage, crit chance, warp/heat/phys resis, deflect value, and so on. Each stat would be increased by 0.5% for each level to a max of 25% at level 50. And for example if you need 2000 levels to max out all stats, make the player only can gain 1000 levels, so we have to pick and choose in what to invest. I wouldnt recommend an infinite level system as other Arpgs do because you would need an infinite scaling mission system like greater rifts in diablo. This system would give a nice long time goal after max level and open up much more builds.
