Grenadier Stryker rework 2

Grenadier Stryker This is variant of Stryker, but less complicated

He has a assault rifle (can be upgraded by buying a exclusive item, and the weapon deals less per shot damage but has a higher RoF(that drops with range, so at his max range he attacks pretty slowly) he technically also has a grenade launcher but that does not count) Abilities Q- launch grenade, launches selected grenade, uses a magazine system, VERY short cooldown in between rounds but ressuplying grenades takes much longer W - Gremlin heal, he sends a drone to heal a target, pretty long range but the longer the range, the lower the heal (only starts after a certain distance E- Precision salvo, he fires a few rounds of munitions at a target, dealing increased damage, multiplies with critical hits. R - Reload, he starts with this ability and any upgrades to this will make him reload increasingly faster, and not be slowed

Exclusive items Every 6 levels he unlocks higher tier gear T1 Plated armour---> T2 Powered armour----> T3 Shielded armour, grants armour and magic resist and upgrades W ability with a better GREMLIN(less dropoff and more healing) And final tier grants a shield that regenerates of combat. Each upgrade costs 1000 gold (or around that) T1 PLR-4_(laser rifle) ---> T2 MST-12(Magnetic rifle)_ ---> T3 APR-24_(Plasma rifle)_. Each upgrade costs around 1000 gold T0 Fragmentation (default grenade, not needed to buy) --->T3 Plasma grenade T0 Flashbang grenade(Silences enemies and reduces attack speed) ---> Sting grenade T1 Gas grenade (Creates a gas cloud that lingers and poisons enemies, the poison lowers damage and ability power) ---> Poison grenade T1 Acid grenade (shreds armour and creates a pool of acid that damages enemies and shreds armour, and covers enemies in an acid that shreds armour) ---> Corrosion grenade T1 Incendiary grenade (creates a field of fire that damages enemies over time and sets them on fire) ---> T3 Phospherous grenade

Upgrade kits for the assault rifle (kind of like the old enchanting thing) Marksman- Raw damage and higher firepower over longer distances (including outranging EVERY ADC) Close quarters expert- CRITS but lower range

Also boots should be integrated into the armor as to let him buy other things (since these 2 upgrade items cost item slots)\

Any ideas or suggestions? Go ahead.
