well...you can use every skill you want, but endless can do 6k ST and calltrops 3k ST, and they are aoe...so it' hard to do good dps and don't use them.
I think there is a broader point that pretty much answers the OP's question. Look at top-tier DPS builds, and specifically at how they use damage layers.
Let's use a hypothetical example of a DW/Bow (class is not important for this example) - suppose that the active skill setup is bar 2: caltrops, hail, poison arrow; bar 1: cloak, rending slashes, whirlwind. [The other two slots on both bars are for passives, utility, whatever.] Let's also assume that So when this theoretical build engages a boss the player can stack the following layers:
- Spammable layer - whirlwind.
- DoT layer 1 - caltrops.
- DoT layer 2 - hail.
- DoT layer 3 - poison arrow.
- DoT layer 4 - cloak.
- DoT layer 5 - rending slashes.
- Additional layers - weapon procs, set procs (if applicable), ultimate (if applicable), class skills/procs (if applicable).
Suppose I wanted to change this build and say - I don't want to get/unlock/use caltrops. That's well and good, but now I lose one layer from my DPS, err, "package". I need to replace it with something, or I need to somehow buff the other skills to make up for the lost damage. If I do neither, I lose DPS by definition.
Same thing if I said - hey, I don't want to use DW/bow, I want to use...2H/2H (! - does anyone actually do this??). Let us suppose I said this. Fine, but now I have to replace or offset the loss of: my spammable, both my bow DoT layers, and both my DW DoT layers. 2H has a better (single-target) spammable (with execute!) and a nice bleed skill, but after swapping those in I am still down three DoT layers that I have to find...somewhere. Could I find them? Possibly. Or possibly not. But whether I do or not will pretty much determine how my DPS for 2H/2H will stack up with DW/Bow.
To wit, if you rebalanced the game to move all the DoTs from the bow line to the 1H line, I guarantee you DW/1H would become very popular very quickly.
My point is that - and this is the approach I try to take, because I do constantly experiment with especially my stamina characters - when you look at an Alcast "top tier" build or what have you, focus on how that build stacks damage, and if you want to change something the first question ought to be - ok, do I lose a layer, and how can I replace or offset that loss?
TLDR - the answer to the OP's question is both a "yes" and a "no". If and only if you can swap out damage layers for something comparable (or not too much of a DPS loss), then "yes". Otherwise a "no".
