It's not the way max OJ's are applied that bothers us. it's the fact our gear is already OJ'd
For example, my Mufflers have
That's completely legit, and with 2 Max OJ's.
But, unless I go out and somehow buy another set of Fatal Mufflers, using one of these Combination Rec Runes will result possibly in the following:
The Max OJ's that we already have in are not "locked in." Meaning, for us to take advantage or be competitive with players who build their gear after us, we have to either scrap our already done Max OJ's, or get new gear (fat chance with rotco leggings, walkers, and tops).
We want a guarantee that the Max OJ's will be ensured.
Maybe offer a Combo Rune promo in a tier that will allow us to max OJ double one stat. For example, my mufflers,
Once done, would be 3800 hp 80 Str 40 Dex 39 Luc.
It's an easy adjustment, and it protects player interests.
Otherwise, I have no problems with the combination system. As I said, it'd have been fine if implemented at the beginning of the game. The reason it's not fine, is because it's being implemented halfway through an expansion, where you have the dilemna of preserving player AP value, and ALOT OF IT. [If I had everything Max OJ'd, I would use 2 per armor (5-6 pieces), or 10-12 OJ's, 4 Accessories X1 OJ (Assuming already one good stat), 2 per wep (8 OJ's in most cases), and one on the cape. That's 25 Max OJ's, or around 325 OP, worth of work, on top of rec rune costs, or 381, 550 AP - Lost to competitiveness.
More stats is okay. We do need to kill quicker.
In other words, I dont think any of your three options are what we are wanting.
