In my opinion, Octgn is mainly a program that succeeds in managing many of the very complex rules, steps and effects of a magewars game. It does so extremely well!
It needs a card database to work, so it is no wonder that a deckbuilder is included. Without knowing I guess 95% of all effort goes into gameplay automatics and optimization.
The spellbookbuilder is also the best there is and is good to use. Even though it is maybe more or less just an add-on.
I see no reason in hating anything here! I see a lot of reasons to say thank you to sIKE and ACG and who ever spends precious time and energy in making a platform like Octgn possible!
What I hate are people who hate around without a constructive background. Maybe I am too sensitive in that point...
