The best thing about Legendary Weapons is their unique ability to change their stat group while out of combat.
Before I made the Juggernaut, I used to carry 2-3 different hammers – all Berzerker stat, but I had one with a Dredge sigil (fractals), one with a Sigil of Speed (for farming) and another that I would change from time to time while I tried to find the ideal sigil.
Once I built the Juggernaut, I figured that the stat selection would be so useful that I wouldn’t need more than one hammer and in one sense, this is true – I alternate between Berzerker for maximum damage and Magi when I want a bit more healing out of the symbols.
I’m currently using the Sigil of Energy which refreshes your endurance after every kill – I’d like to try more sigils, but here is the problem:
1. The “vs. X monster” sigils are very inexpensive and offer high utility under very specific conditions. There are so many of these on the market and their cost is so low that you could easily buy a stack of the ones you need and alternate them as necessary.
2. While continually swapping the “vs” style sigils might be an effective strategy in dungeons and fractals, there are times when you may want to add a more valuable sigil – however once you do this, there is no practical way to recover it for future use. A Transmutation Splitter would work, but it costs many times more than almost any sigil out there.
3. If you would like to have more flexibility, you can carry two weapons (as I used to do) and use your two favorite sigils, or use one weapon with a permanent sigil and the other weapon to regularly re-apply your inexpensive “vs. X” and similar mods as you prefer.
So while it is possible to utilize multiple weapons and multiple sigils to achieve flexibility, this is wildly impractical for all but the most dedicated min/max style players.
One of the major problems is that because the “vs X” weapon mods are so situational and so common, they are rarely used and the market is flooded with them.
My suggestion has two effects:
1. Give players more flexibility in the area of weapon sigils
2. Reinvigorate the oversupplied, underdemanded market for (most) weapon sigils:
Implement Limited Sigil Swapping.
As a starting point, I would propose that:
Exotics Weapons support 4-6 (or possibly not allow this for Exotic tier)
Ascended Weapons support 6-12
Legendary Weapons support 10-20+ (unlimited?)
To add a sigil to your weapon, you would need to acquire 3 of the same sigil, then execute some recipe which would include other items – maybe a gold or ecto sink
After you upgrade/charge/ascend your sigils into some sort of “super sigil” or “sigil essence”, you add it to your weapon and it becomes part of the weapons sigil roster.
This would do a lot of interesting things to the Trading Post and it could spike the market so it might make sense to add some sort of time gating (make it require some of the Ecto refinement?)
It would also allow for some nice customization and give us another dimension of flexibility.
Most people have multiple weapons on multiple characters – how many of them currently use a “10% vs. Krait” sigil right now – not many, but how many people would use them after something like this?
