The problem of the SP was created by the developers when they removed the regeneration of certain parameters (stats) and did not correct the consumption in ReBuild (many skills still have the same prebuild consumption) in a pathetic attempt, in my opinion, that people bought more potion boxes.
What’s more, these changes didn’t even make the Alchemist more viable, its SP potions are still just as useless. In the prebuild, although the non-magic classes had some problems, it was not for these Wizard classes (or magic variants of the Cleric). From something funny that the game had in principle to something annoying and illogical in many cases …
I keep thinking, with the systems that there are currently alternatives to consuming SP (an example, Guild Wars 2?), Are we still using that? So powerless are developers to cast, cooldown and uses as an option to avoid abuse? Almost no one becomes a mage or a technical swordsman to use autoattacks. As a funny note, I often joke about the Tree of drunks (alcoholic beverages = SP potions).
Or Tree of drugs, being more visceral with the compulsory addiction of our characters, who have to look for their “coca” in the market, handcrafted by our favorite camel supplier (Alchemist).
The only option right now is, have an abnormal max SP amount (any piece of gear with max SP and SPR, because SP recovery is a laugh of a parameter) or / and go loaded with SP potions, SP regen cards by kill and bonfires (equip three lvl 10 regen SP card by kill -SPR can help, but is better by kill-, lvl 15 potions from Alchemist, shop SP potions - they do not overlap with the previous ones - and the bonfires and eat some fried fish, to settle down and recover quickly after a minute or two). Some classes have that ability, but they are rare … and expensive, in addition to sacrificing a gap in your Build for just that.
At a certain point this happened, before it was not so necessary to go with the drug on top (SP potions), I think it was in ReBuild.
