As most people said. The basics to get an upped deck is grinding FG, and selling, till you get a working FG grinder; only THEN you are able to get another upped deck for other purposes.
Hence, dekc upgrads are only possible through FG (although you could grind eternally from HB, and have slim chances of getting a upp card from slot machine).
So yeah, i m pro-reducing-upped-cost.
For the argument said of "i worked hard to get my 1500*(number of towers). Its kind of idiotic. I mean, many people had upped cards that were modified (Hourglass, Sundial, etc); so they could argue the same "they should refund; becuase THIS isn't what I paid for" [electrum currency people!].
Therefore, i DO think that they should give a 15 days notice in advance so you get to "save" your electrum from upped towers you have previous to update.
If the 1000 electrum upgrade should be to ALL cards or only Pillar/Pendulum, thats a tricky.
I find that pendulum are important cards of a deck but not sustancial. I mean, obviously no deck works without pillars/pendulum (excepting nova, RoL, fire rush, or any eception of pillarless). And you usually can get more than 6 of the same.
Obviously, it DOES help greatly a deck in having upped towers, as you can grow you quanta stock faster; but upgrades are orientated on cards like creatures or permas. All pillars get the same buff effect from upgrade.
IMHO i would put the upped price on 1000 electrum, as 1500 has only a grinding purpose that can only be achieved trhough FG. 1000 electrum is easier achieve trhough HB (win near 9 matches to use electrum won to upgrade a card), although FG would STILL be a faster mean to get upped cards, either from slot machine, or from electrum (Which need to be buffed, by the way)
