You all need to just dump this sytem since each and every reelase tou take more and more skills and make this ability more and more meaningless. Last release you too almost every buff / shield skill and made staking (which = training) a complete waste of time and effort. this statement also a farce -"[Includes New] Combo Glyphs-The Combo Glyph system allows two Glyphs to be combined during combat into a potentially more powerful Glyph. Combining Glyphs is also called “stacking.” There are two types of Glyph combos. The first are unique combos, where two different Glyphs are combined into a new Glyph for a skill not otherwise available. These unique combination Glyphs often have the effects of both skills used to create them. They cannot be learned as normal skills, and can only be used by combining Glyphs. Check the Combo tab of the Glyphs panel for more details. Second, two Glyphs of the same skill can be combined into a more powerful and efficient Glyph of the same type. Benefits of Glyph combos include decreased Focus cost, additional damage, and more. As many copies of a Glyph as you have in your deck can be combined into a single Glyph, and the stacked Glyph becomes more powerful with every copy combined. Glyphs can be combined by dragging and dropping compatible Glyphs onto one another with the Left Mouse Button, or by hitting the R key and hitting the hotkeys for the two Glyphs you wish to combine. [Includes New] Locked Glyphs can be used for combos." All one gains from stacking / charges more than 1/2 the usable glyphs is a minor focus reduction. Since the patterns is destroy anything a player works towards, just remove the need to train out right and let us use the time for something viable. Or fix the problems that are causing you to consider changes like this in the first place. Eventually there will be soo much frosting on the cake used to try and caver mistakes that it will implode under its own weight. Stacking / charging needs to actually mean something again nit just something you put in instructions but fail to say that for over 50% of the skills this boost is ONLT a miniscule focus reduction. BTW ii was looking specifically at Strength of Earth - 14% for 22 minutes I cast it in preparation and regain the focus back before I even enter the fight so why??????? Go back to letting stacking mean something and work on the other issues . A few of us have already made MANY different more intelligent solution go look at tthem and pick some.
