I get where you are coming from, but in my opinion that will only widen the gap between P2P and F2P.
Refresh it for sure, keep the price reasonable and scopely will more likely sell more on quantity if the quality is there.
Remove 4* toons and weak trainers, cycle in newer 5* toons and bump prestige tokens to an acceptable level.
More people are likely to buy at the current price point if it was a higher risk / reward ratio.
I still buy it because of the daily coins and the remote chance I get a decent toon.
$30.00 per month may seem like a reasonable price point but that will alienate a fair chunk of the player base.
Having two tiered monthly pass maybe an option, but keep the price point the same.
Load one offer with trainers / 4* toons and increase the daily coin collection
Load one offer with extremely rare 4* toons and 5* toons with current coin collection.
That way it’s up to the consumer to decide which one they want to invest in, some months I may be interested in banking more coin daily and could use a trainer where as other months I could go fishing for a 5*
Not that far fetched since 5* toons have been lowered in valuation since ascendancy
Don’t shoot me, just throwing ideas out
