Might be a hard-coded limitation. Many mod authors over the years have sought work-arounds to benefit the game features however very few have been able to get features (like shared affixes) to interact with each other outside of individual affixes.

Next thing I'd like to ask is if anything been done to slow down Charge decay across all classes? I know it won't do much since it'll still require copious amount of Haste applied just to keep an equal footing with player's Pet on its carnage streak.

Interestingly - this is the first time it's been requested.
A "quick fix" would be to mod the Embermage's Charge Mastery Passive to be available on all vanilla classes or even better... mod that to be a Potion effect that can be bought from the General Vendor in any town.

I found a possible work-around in an older mod. Not added to all vanilla classes (on the modded side) however all skills (including the Charge Mastery that has Charge Decay Rate) are available on the 4 (additional) cloned vanilla classes in this mod:

Thanks for a reply.
About Classy Classes. I find 12 skill trees at once way too tempting, so I did even deeper search into Workshop this time.
So far I might found a healthy substitution with merging [Affixes Everywhere], [Pet Equipment], [Tiered Passives], [Unlock All Spells] and [Mastery] into mod list -- simply for offsetting Pet's dominance on a battlefield gradually instead of looming idea of turning into an one-man army swiss knife. I'll check if it works for the latter Acts.

Aggressive Pets aren't tuned right for a Casual Mode, their stats get too high for any Act 1 monsters of equal or a slightly greater level to effectively retaliate against.

You're welcome and that's good to hear on the finds. Inform how the merge performs in case there's any need to spot bugs. I do find Pets to be very powerful in this game and the lesser difficulties would benefit from mods that lower the Pet power although there's very few that do.

It is Mastery Mod v6 what may cause some issues. UNITS\ITEMS\SCROLLS -- dc2_masteriesscroll.dat specifically. Due to insufficient information from the author it's unclear if this item meant to be consumed or even to be present in a loot table in the first place as of current state.
Item description reads: "Right-click to reveal the skills of the Masters, and initiate your training as a Master." However, activating said scroll crashes the game immediately. If it's not a critical bug in the mod's code itself nor an update fault, it has something to do with the same mods listed in my previous post.

Since Mastery Mod hasn't fixed it's issue with it's item; it's best to not include in the merge.
I'd hoped it'd been functional after these past years however it's still too broken for mod-packs.
