Haha, god no. I really like the decision to add a estus flask for your magic bar because essentially it means magic builds get less healing which is a nice balance fix considering how OP magic has been for PvE in previous games.
However as it stands sorcery and miracles very weak damage wise and a lot of people are upset about that. Pyromancy isn't too bad from what I understand
I wonder how many of the "magic was OP" espousers actually ever even played as a caster in any of these games. Probably not many, or else they would realize how ridiculous parroting that is. Melee has always been superior aside from a few instances where ranged is more beneficial. In that event, bows exist. Dark Souls 2 had the most spell variety of them all and gave more options, but in the end most of the projectile attacks resulted in very similar gameplay. Most of the time it's someone who thinks they are awesome at PvP that gets killed by a spell that they could have easily dodged or blocked, so they insist that magic is broken. Or, they love citing Soul Geyser (a spell you get extremely late game, has a single charge by default, has very high requirements to use and also has positional requirements for max damage) as the example.
The only other time magic was "broken" was when abusing Firestorm, but it's not like that was something you used as a primary attack for most of the game. It was mostly for boss cheese, or PvP. Similarly with Dark Souls and Wrath of God/Tranquil Walk of Peace (which got majorly nerfed quickly). For PvE the only truly broken ability was Iron Flesh, and that was patched out soon too. Otherwise, elemental weapons > everything else early on. Magic didn't start getting good in Dark Souls until mid-late game for PvE and you still had to use melee more often than not. In Dark Souls 2, after rescuing Straid, you could have enough Dark Orbs to spam your way through most areas between bonfires, without having to use melee (with exceptions), but it was dreadfully slow compared to just using the fire longsword or virtually any of the other, more powerful melee weapons. Alternatively, you could just start as a Sorcerer, buy 30 more Soul arrows at the start, and another 30 pretty early on in the game. Too bad they did piss all for damage thanks to the early shit itemization for Sorcery, unless you got supremely lucky getting a rare drop from a total of four special enemies, two of which didn't respawn, and the other two were part of a boss fight.
On top of that, offensive miracles got completely gutted by mistake, and FROM never fixed it. That's why I am dubious they'll even bother fixing the current state of magic in Dark Souls 3, even if it is a bug.
