Currently the phase advances not only unlock new units, structures, and technologies, but also increase centre <TerritoryInfluence/Radius> and structure <Capturable/GarrisonRegenRate>.
Players who advance quicker are already at an advantage simply because the new things that are unlocked. These stat changes have a snowball effect, strengthening the stronger, and furthering the gap with those players that are slower, which seems rather undesirable.
Currently garrisoned structures are about 4× as hard to capture in the city phase as the same structures garrisoned by the same number of units are in the village phase.
This patch therefore:
- Removes the structure capturable increases (previously 5 + 7 + 9 = 21 in city phase). To compensate, the default structure value is doubled (from 5 to 10) and territory decay is halved (from 20 to 10), because one garrisoned unit ought to be enough to prevent structure loss due to territory decay.
- The centre territory influence increases , which make sense, are changed to +40% each (1.4 × 1.4 = 1.96, compared to 1.3 × 1.5 = 1.95). Because they compound each other, the absolute area gain of the city phase is significantly larger than that of the town phase.
[EDIT] For the record, concerning <Capturable>:
rP10034 introduced territory health decay (of 20);
rP10048 sharply reduced territory health decay (to 5);
rP16550 introduced structure capturing (including <GarrisonRegenRate> of 3, soldier capture strength of 3) and replaced territory health decay with territory capture points decay (still 5);
rP16779 increased <GarrisonRegenRate> (to 5) and capture strength of champions (to 8);
rP16891 lowered capture strength of champions (to 7);
rP17053 increased <GarrisonRegenRate> (to 7.5) and lowered capture strength of citizens (to 2) and champions (to 5)
rP17564 increased capture strength of advanced (+0.4) and elite (+0.4) units;
rP17060 increased territory decay tenfold (to 50);
rP17062 reduced territory decay (to 20);
rP17077 lowered <GarrisonRegenRate> (to 4), but introduced increases in the town (+1.5) and city (+2) phases;
rP18157 increased <GarrisonRegenRate> to current values (5 + 7 + 9).
