Well put, I feel your pain, good to write about this existing problem. Believe me that Splinterlands was warned about this situation even before kicking in this era of game rules, but they do not want to fix it.

And work out on improving your teams making. View other battles and learn strategies. And if you are running Splinterlands bot, look for better one. I know my friend had far higher win rate when starting to play with basic untamed cards and without booster packs.
