We need to have more skill slots. There is no way 6 slots will ever be enough for endgame.
At Lvl 25, we had 26 skill points. 24 from levels, 2 from exploration/quest rewards. We max at Lvl 100, giving us 99 skills points plus probably 10-20 or so skill points from other sources. There are enough skill points to max out . Assuming 110 skill points. 48 gets us 6 skills maxed out. Assuming we max 10 passives, that’s 30 more. 78/110ish. 32 points left. There’s no way people don’t pick up an extra couple skills. Without more skills slots, these go to waste, meaning we need to go for passives. Meaning that most characters in a class largely become the same with only small variations based on primary skills choice. Then there’s items. Items of all kinds give bonus skill ranks. This includes granting skills you don’t have ranks in. So…why? It’s a complete waste if we can’t utilize the skills we get granted by items. Or, it becomes a carrot on a stick for us to chase items that only grant skills bonuses for the skills we use. And jewelry gives +1 all [type] skills. Big waste. Why give +1 all Mastery skills to grant me access to 3 more skills I have to fight onto my bar? And Necro gets super screwed. Summon skelly/golem not on the bar? No summons for you. Forget that you have nifty curses, Corpse Explosion, and bone skills. If Necro has to run off 4 skills to have summons, massive L.
On the other Hand, if they suddenly say “Hey, once you get your passive at Lvl 33 no more skill points, or skill points every other level” Then we’re getting pigeonholed pretty bad. D2 had just as many skill options and roughly the same amount of available skill points and it had L2 shift. But in D2, we had synergies. Most of our points went into our synergies to fuel our big spammy skills. In d4, with the same amount of skill choices and skill points, we have no synergies, only passives that cap at 3 ranks. And skills cap at 5. That gives us EVERY reason to use 10 skills, but we get 6. It’s all backwards. So, either give us L2 shift for 10 skill slots, or 12 if we can move potion to D pad and make LB a dedicated skill slot, or give us Synergies/Higher max rank. But since launch is 3months away, they aren’t gonna rebalance everything for synergies or rank increases. So, move some buttons around and give us our skills.
