First off as usual PUP delhi Patch notes are always misleading/inaccurate…
Horseman renamed Ghazi Raider
…
- Damage increased from 9/11/13 to 13/16/19
In PUP game tooltips and attack are actually 12/15/18 respectively…
Secondly the War elephant LIVE BUILD seige bonus is +50 in game NOT +100 vs buildings (but at least the PUP updated siege dmg is consistent between notes and PUP build in game).
NOW FOR THE GREAT NEWS!!
Delhi vs HRE is NO LONGER A NIGHTMARE MATCHUP FOR DELHI (and as an added bonus Delhi is even more favored vs English 
)
Ghazi Raiders are JUST the unit Delhi needed that offers a soft counter to MAA that does NOT play into the MAA +6 bonus dmg, plus the Raider having speed advantage over the HRE MAA means they can pick fights, shield crossbows from being swarmed THEN pull back (AKA kiting with horseman*/range units).
ALSO, now that Delhi has a feudal soft answer to heavy units that means Delhi can play long feudal which is often the optimal Delhi playstyle!
LASTLY, I don’t think Zeal works on ALL units on the LIVE BUILD? But it DOES work on all units in the PUP!!
